This story is part of our reporting series, “Covid Year Two: After the Vaccine.” See the full series here.

America’s partisan divide isn’t only bitter. It’s deadly.

During the first year of the pandemic, Democrats died at higher rates than Republicans. But during the second year, as Covid vaccines became widely available, Republicans in San Diego County began dying at significantly higher rates than Democrats, a new analysis by Voice of San Diego found.

That finding might sound familiar. But other prominent analyses only surmised Republicans died at higher rates, by comparing Covid death rates to voting patterns. Voice’s analysis actually matched the names of people who died from Covid in San Diego County to their political party affiliation. 

Republicans were 39 percent more likely to die with Covid during year two of the pandemic, even after adjusting for the fact that they tend to be older than Democrats. Independent voters — who belong to no political party — were also 30 percent more likely to die than Democrats during the pandemic’s second year. 

In all, at least 534 San Diego Republicans died in year two of the pandemic. During the same time, at least 405 Democrats died. But for every Republican in the county there are roughly 1.5 Democrats — which accounts for the widely varying death rates.

“It disturbs me significantly,” said Greg Cox, a Republican and former county supervisor, who helped lead the local response to Covid. “Does it surprise me? No, not really. I would assume it was because of the influence of some people in the Republican Party who made a concerted effort to convince people not to get vaccinated.”

The death rates roughly align with trends in vaccination rates across the country. In September 2021, 92 percent of Democrats reported being vaccinated. Among independents, 68 percent were vaccinated. And among Republicans, just 56 were vaccinated, according to Gallup

Voice sued San Diego County to get access to local Covid death certificates as part of its investigation. After winning the lawsuit, reporters spent months manually logging each one that listed Covid as a primary or contributing cause of death between March 2020 and March 2022. We then matched the name of each person who died to their voter record — if they had one listed on the county’s public voter roll — to learn their actual political party. 

Previous reports have analyzed Covid death rates in counties that tend to vote Republican versus those that tend to vote Democratic. But those reports left unanswered the question of whether actual Republicans were dying at higher rates, or whether something else might be at play. 

Another study matched death records to voter rolls, but instead of looking specifically at Covid-related deaths, it focused on “excess deaths” — a public health term for the number of deaths above and beyond those that normally occur. That study found excess deaths were 76 percent higher among Republicans.

Researchers and public health specialists interviewed by Voice pointed to vaccine resistance as the most obvious reason for the widely differing death rates in San Diego County. 

“The vaccine was definitely at play in this,” said Ming-Hsiang Tsou, a geography professor at San Diego State who helped local officials analyze how the virus spread. “Attitudes towards vaccinations are hugely different among the political parties.” 

A previous analysis by Voice also found that death rates shifted drastically across the region during the second year of the pandemic, moving into more conservative-leaning areas like Lakeside and Santee. The finding was especially striking since death rates went down in virtually every other ZIP code in San Diego County after the arrival of vaccines. 

Rebecca Fielding-Miller, a public health professor at UC San Diego, said the difference in death rates might also be related to “a whole behavioral package” — including people’s willingness to wear a mask or avoid indoor gatherings — that separated the two major political parties. 

People are also increasingly socializing in a bubble with others who share their ideological perspective. That creates “an effect multiplier,” as Fielding-Miller put it. People tend to make the same choices on masking or other Covid precautions as the others they’re hanging out with. “The social norms reinforce one another,” she said, “and you are in a social network with much higher risks.”

The local death rates show Democrats were significantly more vulnerable to Covid than Republicans in San Diego County during the pandemic’s first year. And on the whole, Democrats do share many characteristics with those whom the virus hit hardest. People of color, who are much more likely to be registered as Democrats, are also more likely to live in multi-generational housing and suffer from underlying health conditions. Democrats also are more likely to work low-wage, public-facing jobs.

When comparing the change in death rates between years one and two, the differences between the parties become even more stark. Democrats’ death rate dropped four times more than Republicans after vaccines became widespread. 

The death rate among Democrats dropped by roughly 53 percent between years one and two. It dropped just 13 percent for Republicans and 25 percent for independent voters. 

Most independent voters actually lean one way or the other politically. Roughly 48 percent tend to support Democrats and 39 percent tend to support Republicans, Pew found in 2018.  

Even though independents are split ideologically, they do have one underlying characteristic that aligns with traditional Republican politics. Independents across the spectrum tend to express a greater distrust of government — which may have played a role in their willingness to receive the vaccine. 

“It could really well be that the distrust translates into the public health arena,” said Seth Hill, a political science professor at UCSD. 

Republican and Democratic trust in government, on the other hand, tends to fluctuate depending on which party is in power, said Nicholas Boushee, a professor of political science at San Diego City College. 

Republicans lost control of the White House just as the vaccine was becoming widely available, which might have amplified their distrust. On top of that, the party’s leader was sending out mixed messages, Boushee said. 

Donald Trump took credit for the vaccine rollout and even called masks “patriotic” at one point. But he also questioned whether they were effective at stopping the virus and mocked his opponent for wearing one. 

Supervisor Nathan Fletcher, a Democrat, led the county’s response to Covid, along with Cox, the former Republican supervisor. He remembered an early press conference at which Republicans and Democrats had been completely united on their response to the virus.

“It had this kind of post-9/11 unity, like, ‘We’re all gonna get through this hardship together,’” he said. “I remember walking back to my office wondering how long that was gonna last.” 

Once the political fracturing began, the level of misinformation in conservative circles became egregious, Fletcher said. “I understand if someone says, ‘This is America, you can’t make me cover up my face,’ but that’s not what we were fighting,” he said. 

Instead, people argued that masks somehow made the virus worse and that vaccines, rather than the virus itself, were actually killing people. Eventually, county meetings devolved into hours of angry, even hostile, remarks by anti-vaxxers. 

“It’s heartbreaking that people were led to believe these things that were not true,” Fletcher said. “I feel bad for them, for their family members, for their kids. It’s just a heartbreaking outcome of the politicization of public health.” 

The death rates between political parties were fairly similar among the very young and the very old. But death rates within the age cohorts between 45 and 75 years old differed widely: Republicans were more than twice as likely to die as Democrats in some of those age bands. 

To perform the analysis, we first matched records of people with the same name and birthdate. To account for errors in data entry, we then used an algorithm to seek out near matches. We manually went through each near match and, with the help of addresses listed in both documents, verified if it was an actual match. 

During year one, roughly 4,200 died with Covid in San Diego County. We matched 41 percent of the year one death certificates to a voter file. In year two, roughly 2,200 people died. We matched 57 percent of the year two death certificates. 

One likely reason we found fewer registered voters in year one is that immigrants — at least some of whom would not have been eligible to vote — died in such disparate percentages during the first year of the pandemic, as Voice previously reported. That disparity decreased during the second year

In California, roughly 60 percent of people 18 and older are registered to vote, according to Census data. 

When looking at raw, non-age-adjusted death rates, Republicans were actually twice as likely to die as Democrats during the second year of the pandemic. But Republicans, as a group, are older than Democrats and Covid is a virus that disproportionately kills the elderly — a set of circumstances that necessitated age adjusting the data.

“Any death is a tragedy, Republican or Democrat,” said Cox, the former supervisor. “I would hope the Republican Party would begin to get a broader view of what public health is all about. And we should all work together to make sure we have the best public health system we can. It’s about the survival of parties but more importantly the individual. Whether someone is Republican or Democrat should be immaterial.”

  1. So now you have individual voter registration, death certificate, address and what other information on how many people. That would like very sensitive personal information. I hope you will be responsible stewards.

    It’s interesting that we (and you) often talk of big tech harvesting personal information, running it through algorithms and using it for personal purposes. I think you need to include the media in that conversation.

    1. Voter registration is public information. Your name, address, party and if you were dumb enough to provide it, your phone number.

      1. No it isn’t. That information is only supposed to be available for people running for office that have a need to know for it. The average person isn’t supposed to have access to that information just for their own person use. Last time I had access to that data to volunteer for a candidate I remember the rules and regulations for use of the data.

  2. Finally, after pointing to masks, gathering etc – basically trying to call Republicans “stupid” – there is finally a reference to age. Why wasn’t that up front? Especially now that we know deaths have a correlation with age? And of course, there is an inflammatory headline about political party. Partisan much? What is the point of this article?

    1. It’s a simple fact that more unvaxxed people died than vaxxed people, and more conservatives are unvaxxed than liberals. This has been shown over and over again across the country. This article just dives into the numbers specific to San Diego County. Just because you don’t like the conclusion it doesn’t mean it’s biased.

      1. I would like to say that I have read this story 3 times now and no where in it does it say how many of those deaths were from the vaccinated or non vaccinated. So the specific numbers to San Diego which you reference are not there, and as far as non vaccinated died more than vaccinated is probably going to be true for a while because we did not have a vaccine for over a year. If you want to make a informed decision on this matter you should get all the information that is out there, and I don’t think this reporter is informed at all . He is pushing one sides agenda and that is why those numbers were not included in this story. One thing that is true is that being vaccinated does not stop you from getting the virus, or transmitting it and as far as it being not as lethal, I have yet to see a study that proves that. All the studies I have seen do not include all the facts.

  3. I noticed that you never said what the numbers were for people who were actually vaccinated verse those who were not. Why did you not mention this? It seems to me that this would have been a much better study. I could tell from the start of this story which way you were leaning. Next time maybe you could include some facts that really matter, instead of trying to divide us even more. We have plenty of things to divide us right now like this Idiot that we have as a President, don’t try and make things worse. I would like to hear those numbers if you have them, and if you do why you did not include them in the story. I have my own theory on this, but will refrain for now. I would also like to know how many of those deaths were from people who had covid prior to the vaccine coming out weather they were vaccinated or not. These are the things you should report on , facts that matter so we can all make informed decisions. What I see from a story is that if you would have listened to us Democrats and took the vaccine like we told you to then your family and friends might be alive now. Which may or may not be true, but one thing is for sure without those questions being asked no one will know the truth. I’m sad to say that I think that is the way you want it. A true reporter will report without bias, remember that next time. I don’t think you will publish this, but prove me wrong.

  4. This holds true across the country for everywhere they’ve looked (though it’s good to have more solid data like this). Being unvaccinated, obese, and/or old means more covid deaths, and the people least likely to get vaccinated were immigrants and MAGAs. Hispanics over all actually got vaccinated at a higher rate than Caucasians, but immigrants as a whole have other issues – some of them they had little control over due to their employment circumstances, but also vaccine fears.

    MAGAs, on the other hand, deliberately demanded not vaccinating and not masking as a group identity political statement, so died off in much higher numbers in order to pwn the libs. Trump changed his position later, but ironically his initial political stunt ended up wiping out proportionately more people who would have voted for him than against.

    1. How do you explain that independents died at essentially the same rate as “magas” as you so ignorantly call them?

    2. Very interesting how you refer to MAGA’s , you know the people who wish to make America great again which you are not having any part of. Maybe you believe in the inflation reduction act, that can’t reduce any inflation that cost us how many trillions of $, Maybe the build back better plan, more trillions of $. I bet you think that the Hunter Biden laptop story is just Russian disinformation. One thing is for sure, if I go out and get a bunch of credit cards and charge them to the hilt can I count on you to help me pay that debt for the next 50 years or more. At least Trump was trying to help Americans unlike the idiot we have now. Maybe we should all just drive electric cars, that will solve all the worlds problems. Maybe we could just get Idiot Joe out of office , that would be a much better solution to the worlds problems. Maybe we could just elect Hunter next time;

    3. What would have made for a better story would have been for them to include all the data, and not just what fits there narrative. Like an unbiased reporter would have done. Data driven reporting just don’t include all the data. You can’t tell me that nobody asked those dying MAGA’s if they were vaccinated or if they had Covid before.Why not ask the Democrats and the Independents that were dying the same question, now that would be some data driven reporting. Hell they could have just taken out the words MAGA’s , Democrats and independents and had a real story. Why was that information withheld from the data driven reporting ? Because it doesn’t fit there goals to keep the country divided, that is there narrative. What better way to show they were right than to tell you that they were right. If you just keep telling lies it will become true someday, just not to the people who keep asking the questions. This reporter will never show you all the Data, because then you could make up your own mind instead of there narrative.
      Sorry folks but these are just the questions that pop into my head when I read a story like this, Maybe we can try and include all the Data next time and not make it so one sided. Just a thought.

    4. You my friend are an Idiot, the facts are in. You could not be unbiased if your life depended on it. That is why you will always vote with the Democrats, cant make these kind of decision on your own, They know whats best for me, they always have my back. Do you still think the laptop story is Russian disinformation? You do know the truth about that don’t you. OMG you still believe that story.

  5. Excellent article. Great investigative reporting by Huntsberry and Marx. One more reason to keep supporting our local voice–Voice of San Diego!

    1. I think an intelligent and educated person might try reporting this story using all the data at there disposal. Instead they only use what fits their narrative. What is so intelligent about a reporter who reports a story, but purposely leaves out important data to sway his readers in one direction or another ? I will take a wild guess and say that GF and MR are not, and never will be Republicans . Maybe next time you could get that education , and intelligence from someone not so Biased .

  6. Oh yea! I was a Democrat for the duration of Covid and the 48 preceding years until I quit! I’m 70 an endurance athlete, seldom wore a mask, got no vaccination and never got sick! OK, I lied! I was sick once in 1973. I think I had a cold. Maybe these people ought to stop Krispy Creme and Jack in the Box! Maybe they ought to drive slowly and run fast and not vice versa. Maybe they ought to examine their own wasted lives? Smiechowski

  7. No one believes your numbers. What people are beginning to believe is alot of people are dying suddenly. No one knows why? Can’t figure it out. Too complicated.

  8. I am wondering how many have died from heart/stroke issues with the experimental Covid shot?
