The chattering classes are starting to talk about impeachment. I've seen the statement that if the Dems take the House in 2018 Trump will be impeached.
That may well be true, but I see nothing on the current horizon that says he will be convicted by the Senate. Remember the Reps are odds on to retain control of the Senate. Even if they don't, conviction requires 2/3 of the Senate. There's no way to convince that many Rep senators.
What should be considered, assuming there's substantial cause, is what the Dems offered the Reps in 1998, and what was actually passed in the case of President Jackson, a resolution of censure.
