Trump won’t lose his supporters...the Nation may turn on GOP who dont support him and if they impeach him well it would have to go thru the House Impeachment process and Senate Trail so before that happens I do believe Trump supporters will be out with pitchforks and torches or other forms to show dissastisfaction of the uni partys leadership
The GOP in Congress is a disgrace. Actually, so many of them are being threatened with their FBI files that they don't dare take a stand.
It may finally occur to the Republicans in Congress that refusing to support Trump is suicidal. In fact, the Democrats' talking up impeachment may be the main incentive for voters to vote for the Republicans in 2018.
