Lets Get Real:
It can be fair to say that President Trump is the WORST President in US history, he has been impeached twice, and on the 2nd one he did that to himself. The speech outside the White House roused the rioters to attack the Capitol. It is expected that Trump will use his PARDON power for his friends and himself, on the pardon to himself, that might sound crazy but he should not expect that Biden will be giving him a PARDON, thus if he removes the problem by doing it himself, the Washington D.C will give the impression that they are annoyed but might be just as happy for the issue to go away. As for the comparison with Nixon, Tricky Dicky won two elections, and resigned before he was impeached. Also the Nixon years had success on the domestic front and on the World State, that is more than be said of Trump. On foreign policy Trump has been a disaster, he makes Jimmy Carter look good and he never be another Reagan. Thus we start with the Biden Era.
