I read that for this impeachment thing, the tie would be broken by Judge Roberts.
I heard Ted Cruz talking several days ago that he thought it would be better to have the trial and find Trump innocent of the charges than to just dismiss it out right, as that still leaves the idea of “impeachment” out there for the democrats to harp on.
The final vote for Clinton was 50-50. No tie break needed for the verdict because 67 votes needed to convict.
Roberts can’t vote in the senate.
