Are people really surprised that the trial will fail? Senate is still very much in contention and the US is very much split on party lines, and was long before Trump. That 5 republicans voted against their party is the biggest surprise here.
The Senate will not vote to impeach. Clear as day. You won't get 17 republicans voting for it.
Better luck in the courts (I hope). But if the cases hit the Supreme Court, that will be the interesting case. See if judges follow the law or their political affiliation (yeah, like that's an unanswered question).
