So...whyt if his reason was...he was 22 and sick of the garbage he was paying for...hhmmmm...how will that go over?
That probably depends on how his answer comes across. If it's genuine and sincere, and he can segue from that to his accomplishments as governor, it might be able to work for him.
But if he comes off as arrogant, as if he was somehow above college, maybe not as much. Despite many of the leftist liberal arts degree programs out there, most people have to put up with crap in their jobs and everyday life. While I didn't agree with many of my professors and instructors in college from a political point of view, I did the work, and I got out of that class. This is life. You don't always have the best manager, you don't always have the best customers or project team, but you still have to make it work sometimes. You can't just say (very often), "I'm sick of your garbage, and I don't want to work with you any more!"
