There is no need for Evidence. There wasn’t when they impeached Trump. All they need is the majority (the Republicans) to VOTE for impeachment. Voila.... Asterisk goes by Xiden’s name.
You’re right, but see above. All you need is a majority — a big enough majority. The vote against Trump impeachment was 7, 3 Dems and 4 did not vote or voted present.
If we had just 7 refusals, we don’t even get out of the House to the Senate.
IOW, the majority is not big enough to do this.
