Republicans in 2021, but by 2022 around 700,000 Republicans had refused vaccination to spite Biden and then died from COVID, and their absence was noticeable in the 2022 results.
So Democrats on balance, and the effect is likely to be visible for years.
The only way you get this is by attributing 100% of covid deaths from 2021 and 2022 to Republicans. In addition this being an extremely presumptuous and bigoted thing to say, it's also wrong (so par for the course for you!)
Rates of covid death remained higher for Black and Hispanic Americans in both 2021 and 2022.
