From the Twitter post:
talking about the study at:
"New study of almost 600,000 deaths in Ohio and Florida shows that registered Republicans had far higher excess-death rates than registered Democrats during the pandemic, with almost all of the gap coming after vaccines were available."
"The study shows there was no difference in excess deaths between Dem and GOP voters in 2018 and early 2020 (control). And there was no real gap pre-vaccine. But beginning spring 2021, and accelerating w/Delta Republicans began dying at a significantly higher rate."
"This paper is based on individual-level data (that is, the authors matched mortality data to individual voter registrations), which makes it more accurate. And the clear implication is that if Republicans had gotten vaxxed at higher rates, many more of them would have lived."
"A note on methodology: looking at excess deaths, rather than total deaths, mitigates the "GOP voters are older" issue. And the fact that there's no meaningful difference in excess rates during 2018 or even the first 7 months of the pandemic suggests that vaxxes made a difference."
"One other thing to note: this study looked at excess deaths, not Covid deaths. So if the vaccines were killing people, you'd see it in this data. You don't see it, because they're not."
PS: It is a working paper, and not peer reviewed. It was purely a data driven study done with available voting registration data and excess deaths data both pre and post vaccine. It is printed in the NATIONAL BUREAU OF ECONOMIC RESEARCH and not a medical journal and the person you are quoting from Twitter is a business columnist who blogs on the economy...
