Let's be real. I don't think a single person that waits all day in the wind or the cold to attend a Trump rally would ever vote for Biden. It takes way too much dedication if you're just thinking about voting for Trump
Only way trump loses this election will be due to the obvious ballot box stuffing the libs seem hellbent in executing.
Extend ballot counting through the election for as long as they can and use that time to find where they need to add numbers. Insane you say? Look at the gubernatorial election in Georgia and the 2018 midterms.
