“GOP want a Democrat to win so Trump can be impeached”
The only thing that stands between President Trump and removal is the fact that Ryan (Romney) needs 25 GOP Members to vote with all 193 Democrats to send Articles to the Senate.
There are 19 GOP senators who would vote for removal tonight - hell, there are probably 30. The number of Democrats in the Senate is of no importance for this issue.
I think you are correct. The GOP is behaving in a way to lose both the House and the Senate. Then the Uniparty can move to impeach and try to remove Trump. The GOPe desperately wants this, but will then sit back and disclaim responsibility.
