They believe their own bullshit that they circulate in their echo chamber of delusion. Think of how brainwashed one would have to be in order to think that they could commit treason and rig a Presidential election, all with overwhelming evidence to implicate them, and actually get away with it.
If I were one of these traitors (politician, judge, lawyer, MSM, etc…), I'd be quivering in bed at night with every day that Trump just Tweets and the FBI & DOJ & Military stay silent. The funny thing is, they can't see the tremendous hammer that is about to fall on their asses.
