Wishful thinking that a Republican congress would impeach him. He'd have to do something to deserve it first, and it's a difficult process that failed with Andrew Johnson and Bill Clinton.
Personally I believe if he continues the road he has taken, coupled with his lack of political experience, both sides of Congress will see to it that he is out before his first 2 years are completed, perhaps sooner if he really messes up.
With Trump at least there is hope with Hillary there was less than nothing. She was in it for the money and power not for any great love of America. She proved that with her pay for play run. If you look at the condition of our government, only someone like Trump (a real rough around the edges scrapper) would have the guts to go against the stream and try to bring a change. I just hope he is successful.
