Overall Popularity. Trump is popular. He received more votes than any other sitting president in US history. 73 million. He has huge support with his base and a high % of the time the incumbent president always wins reelection unless he's unpopular. Biden is unpopular compared to other presidential candidates in the past. He ran and failed twice before. https://www.newsweek.com/donald-trumps-736-million-popular-votes-over-7-million-more-any-sitting-president-history-1548742
Attendance. Trump packs large arenas and stadiums regularly. 20,000+ have shown up at times and are high enthusiasm. Biden's rallies are poorly attended, mostly small, sometimes less than a few hundred attendees with low enthusiasm. Sometimes only 10 people or less would show up. https://heavy.com/news/trump-vs-biden-tampa-rally-crowd-photos/
Campaign frequency. Trump campaigned longer and harder than anyone else in history, giving unprecedented rallies 3-4x a day sometimes in multiple cities day after day, hundreds of them. Biden stayed in his basement and hardly campaigned in 2020 and did maybe 10% or less what Trump did. https://www.thegatewaypundit.com/wp-content/uploads/Trump-vs-Biden-Rallies-9-21-20-1536x789.jpg

Reports. Many videos and testimonies of fraud. Too many to list here.
So, we are supposed to believe that a man in his late 70s with memory problems who ran and lost twice before, who hardly campaigned, who has 25% fewer social media enthusiasm, who has ties with China, who is under FBI investigation, who is called a sexual predator and caught on videos touching little girls, who did far less rallies, had far less attendance, but somehow got more votes than Obama or anyone else in US history?
America knows who it voted for, and it wasn't Biden.
