The impeachment also is absolutely impossible without both the house and the Senate. If the Democrats win the house, but not the Senate, the Senate is just going to vote down every single time they are able to impeach. If the Dems win the Senate, but not the house, barely any impeachments are going to happen at all
Personally my bet is that even if an impeachment were possible that our lawmakers would stop short of actually sentencing him to any sort of prison time. Democrats in office today would absolutely rather let him go free than take the risk of creating major conflict by jailing him
