If you want to pretend that Russian collusion was a fabrication, you have to explain why Senate Republicans found that Paul Manafort was exchanging internal campaign data with a Russian Intelligence Officer. So far, no one who I have encountered who believes that collusion was a hoax is able to explain this uncomfortable fact.

Here's what the Senate Intel. Committee concluded:

  [B]ased on the facts detailed in the Committee's Report, that the Russian intelligence services' assault on the integrity of the 2016 U.S. electoral process[,] and Trump and his associates' participation in and enabling of this Russian activity, represents one of the single most grave counterintelligence threats to American national security in the modem era.

Again, that was the conclusion of the Republican majority Senate Select Committee on Intelligence, chaired by Republican Richard Burr. What about this is a fabrication?

What happened in 2020 is not that the election was more secure per se (although there was some foreign interference reported at the time, it was not as bad as in 2016), it was that Paul Manafort was not Trump's campaign manager. He was the main vector between the Trump campaign and Russia. And honestly at that point, Russia didn't have to do any work to get their propaganda on American airwaves, because Fox New was literally doing their job for them -- e.g. broadcasting the position that Ukraine was responsible for the 2016 DNC hacking, not Russia.

> the transfer of power turned out to be mostly peaceful - as usual.

Mostly peaceful? A violent insurrection at the Capitol during a joint session of Congress, sent there by the defeated President, with the explicit intention of preventing the transfer of power through force is not "mostly peaceful", I'm sorry. It actually marked the ignominious end of a 200+ year streak of peaceful transfers of power. Even during the Civil war something like 1/6 didn't happen.
