A “majority” means nothing. You need 2/3 to convict in the Senate.
Understood. But if a majority of the senate votes to convict, then there is bipartisan agreement, and majority agreement, that Trump is unfit. The press will beat the "majority" drum hard.
The press will say that 2/3rd rule is bogus, blah blah blah.
My point was that the Senate is mindful of the majority threshold, even though it has no "legal" effect, it has substantial PR effect.
