I have an excel spreadsheet comparing the 2016 results vs the 2020 results BY COUNTY in Pennsylvania.
I lack the skills to post it myself so if someone can post the spreadsheet on FreeRepublic, send me your email address via private mail and I can send the excel spreadsheet to you.
If you put your data on OneDrive, you can post a link to that location, here.
I have the results for 2012 and 2016. What are you needing me to do with the data?
