Corker made the deal possible. Many people warned the deal would be a disaster. Corker was either a willing accomplice or a complete idiot. Either way he is unqualified for office.
He is up for reelection in 2018. The people of Tennessee reelected him in 2012 with 64% of the vote against a conservative Democrat who was disavowed by the DNC. Will a conservative primary him in 2018?
Corker and Lamar Alexander are both RINOs and are unfortunately my senators
The dude who ran against Corker as a democrat was a conspiracy nutbag, far from a normal conservative. His chances of winning were 0%.
Joe Carr (ran against Lamar! in the primary last year) should give it another go. Or another serious conservative Republican.
