There's your impeachable offense, right there.
The DEMs have set the standard, and if it's a bad standard, the best way to abolish it is to apply it. This was done with the DEMs abusing cloture in the Senate, to enable a minority veto to confirmation of qualified judges. DEMs started it, GOP continued it, DEMs then abolished this particular abuse after it was applied to them.
Exactly. The only way to stop them is to turn the political and impeachment guns on them.
