Can you provide specifics regarding your feelings about his unfitness?
As for his ability to win, I think there are more conservative voters out there than the media (and the Republican Party leadership) lead us to believe. The GOP keeps fielding moderate candidates. I’d really like to us try a strong conservative–fiscal and social–candidate for a change.
Cucinelli, for instance, came extremely close to winning. He was far outspent by his opponent, partially because the GOP stop funding him in October. If the GOP would actually back strong conservatives, instead of going on the attack like they did against Ted Cruz recently, and against Tea Party candidates during the previous election, they would be much stronger candidates.
