Of all the leftwing yakkers Scarborough has the least credibility, as a few years ago he was mouthing all the right conservative platitudes. He's found his niche and it must pay well.
He is probably a role model, for Jeff Flake.
This time around, the casting urinal will be crowded, with Flake, Corker, Will, Kristol, Sasse, McMuffin, Ryan plus other contenders.
All carry the "conservative" label.
