1. Did you know that about 1 and half years before the election and while Biden hadn't still publicly declared his interest in running for the presidency (though everybody knew), Trump and his lawyer Rudy Giuliani told Ukrainian authorities to start investigating Joe and his family because of a contract his son executed in the country?

His intention was that such investigation would damage his reputation back in America (even if he was innocent) and make him to drop his ambition to contest.

When this leaked, this later led to Trump's own investigation and impeachment .
It was similar to the Watergate scandal in the 1970s that led to Richard Nixon's resignation.

If Trump truly saw Joe Biden as a walkover, would he have attempted to smear his name by pressuring a foreign country to find dirt on him? No.

2. In one of his rallies, Trump said he would leave America if he loses (it was a morbid fear because he knew what awaited him)

Childish assertions like Obama didn't use the FBI to bully Trump while in office
