Trump will be fine. Impeachment will never pass the Senate, and the Dems look like total hypocrites for their language on Trump vs Clinton. The basis of the whole thing will knock Biden out of the race, putting a total loser like Warren in as the Dem nominee, the voters will be annoyed and Trump will quite probably win a second term.
The Dems will learn absolutely nothing from this, and spend all of his second term trying to dig up some new scandal on him rather than conducting the business of government. Again.
