If anyone is interested, I have a similar market for specifically how many times he gets impeached conditional on re-election, from 0-5+ https://manifold.markets/Dfe2f/if-donald-trump-is-reelected-how-ma

If Donald Trump is re-elected, how many times will he be impeached during his second term?

Resolves to N/A if Trump is not re-elected or otherwise fails to start a second term, otherwise resolves either upon completing his second term or leaving office for any reason before then.

The chance of this happening is probably about equal to the chance of Democrats holding a House majority at any point during his term.
