I've compiled some covid data, and I think adding some political leaning data might make it a little spicy. I've seen some maps of political leaning for counties, but I cant find a source. I'm looking for a data set that has counties (or states, preferably counties) that show their political leanings. Hopefully in a simple format, like +4 Democrat or +4 Republican.
538 has a pretty cool election forecast page:
you can get a direct download of the polling data: https://projects.fivethirtyeight.com/data-webpage-data/datasets/polls.zip
they also have a data page at github that links other CSVs and explains the data model: https://github.com/fivethirtyeight/data/tree/master/election-forecasts-2020
