The Republican senators who were literally ushered out of the Capitol in tears while armed thugs stormed the building in a literal coup attempt, as directed by the President, to overturn the election and stop the Democratic process, refused to even vote to impeach the President that ordered and orchestrated the whole thing.
That's how batshit partisan it gets. A President could literally murder and rape someone on the floor of Congress and they wouldnt vote to impeach (presuming the President in question was from their own party, and had sufficient public support).
It's madness. They've all but set a precedent for such behavior.
This blood is on their hands as much as it is on Trumps.
