I grew up next door to Minnesota. Dayton is a handsome face who couldn't even hold down a job in a successful business started by his father. He's made a career out of running for office. He gets elected only when his opponent (or in 2002, his opponent's son) does something really, really stupid.
However, once in power, he can coast on name recognition alone because he does so little to offend anyone. This, of course, does not include the politically astute minority who is offended by him relaibly voting the liberal party line.
