It just sounds to me like he’s suggesting that people would mobilize opposition to Hillary’s judicial picks. The MSM is in a panic today trying to deflect attention away from the fact that Hillary’s campaign invited the father of the Orlando Nightclub terrorist to share the stage with Hillary.
That's exactly how I read it to mean - they'd be driving their congresscritters bonkers. I, for one, would not want Mr. "The Shining" Kaine appointed president and I doubt any other sane person would either.
