The Democrats have yet to identify a crime. "Abuse of power" and "Obstruction of Congress" are not crimes codified in law. The list of impeachable offenses is very short and very specific.
Treason, bribery, high crimes, misdemeanors
The democrats tried to sell bribery - but that didn't work, they have yet to determine what high crime he has committed, and they have yet to identify any misdemeanors. It's a show with no plot.....it's Seinfeld, but not in any way funny.
