Nothing truer has ever been said, but it appears that Republican Senators care more about saving themselves than saving America.
Yes, they feel if they vote to impeach Trump and find him guilty, they themselves could inflame Republican voters.
If they are so, anti-America and pro-themselves, then they should not be in the Senate, for they are there for the wrong reasons.
For America should come First.
