1. An incumbent wildly popular with his base always wins re-election.
2. The candidate who wins all of the bellweather counties (except one, I think) always wins.
3. No way did Biden get 17 million more votes than Obama at his most popular.
4. There was no reason to refuse to count the mail-in votes until the in-person voting was done, unless it was to ensure that enough mail-in votes were generated in the correct swing states to steal the election.
Those four things are all I need to know in order to ascertain that there was massive fraud.
And state election laws were broken in 2020 under the cover of Covid-19.
