I did a similar study a week or so ago and got similar results:
Democrat Led States + DC = 23,447 deaths
Republican Led States = 4,999 deaths
Be sure to include Washington DC in your numbers as that has been Democrat led for decades.
With so many deaths concentrated in a single state (or two) - NY and NJ, this is ironically a good explanation for why a national popular vote is a really bad idea for the USA, ironically enough.
