If it does, and he's impeached, I fully expect the US to be crippled by weeks (or potentially months) of civil strife. There are people who legitimately think that he's done nothing wrong, never lies, is a "man of his word" and is basically the second coming of god. The Russia inquiry could have a 12 hour newscast stating all the evidence against him, basically say that he's an illegitimate president elected fraudulently...and his "base" would load up their AR15's, light their flaming pitchforks, and run into the streets screaming "FAKE NEWS!".
Because you know if Trump does take a fall from grace he'll be having a full on twitter ****-fit for years afterwards claiming his innocence and kicking the hornets nest.
There are people who despite the confirmation from all branches of US law enforcement saying otherwise) who think that Russia didn't interfere whatseover in the election, regardless of what the inquiry finds.
Trump could stand in front of a microphone this afternoon and state that the earth is flat and his base would then argue the point to their death...because whatever Trump says is the gospel - reality, facts, science and everything else be damned.
