Good. Let them. The best possible thing that could happen right now is a yes vote on impeachment. It would send the whole shitshow to the Senate which pulls a majority of the leading Democrat Presidential candidates off the campaign trail and gives the Republicans in the Senate subpoena power to call Biden, Schiff, Pelosi, Hillary et al to testify under oath in front of a hostile body.  At this point the Democrat's choice is to admit this whole thing was a sham and not vote, or go ahead and continue down this road where the Senate will break a dick off in their ass. This thing is the gift that keeps on giving for Trump.
