Hmmm...
Everything above board and within all past Democrat (now Communist) election victories going back to 1948...
Although I saw, in person, some things in the 1944 election that looked suspicious...
Folks will laugh at you, but you’re literally telling how it was (numbers may vary). You really do have dead and illegal voters, a sudden 2AM surge for Biden in all the key states where he was behind, a massive increase in mail in ballots (because of Covid) and cases of ballot harvesting...
IMHO and I’m not a pollster or election expert: Biden and his team simply had a huge advantage in knowing how to game/manipulate the election policies and procedures to ones own advantage, and he had a Congress and MSM that was supportive.
Trump wasn’t a real politician, many of the folks around him neither.
Biden on the other hand was in Congress for like 37 years and ran many campaigns, he was a VP, and then ran for President. He knew the games and the people.
But that’s just my stinking opinion.
