Wishful thinking but it's okay to dream. Let's be real though. Even if Nancy and company bring impeachment forward, no way in this or any other life does the Senate convict.
Trump certainly won't resign. If I'm in charge of the Dems, I let this thing sit on the back burner. If we beat him next November, he's gone forever. If we incite his troops to riot and he doesn't get impeached, he's here for four more unfettered years and there will be hell to pay.
Smart money says, find a good candidate and beat him on the issues.
