Haslam won the TN gubernatorial primary in 2010 because he was the only Leftist Republican, while Ramsey and Wamp split the conservative vote.
Bredesen is not your typical Democrat, but he is still a Democrat.
Rauner has been good... for an Illinois politico.
If Trump really wants to keep his brand of being the one true anti-establishment candidate (Sanders and Cruz are both career politicians), he should not choose a politician as a VP, especially since that politician will inevitably be bribed to participate in an assassination of Trump.
Probably a correct analysis. Luckily, Donald Trump has a pretty good track record as a talent scout. :-)
