Dynasty Fatigue?

I wonder how many people, either consciously or unconsciously, will vote based on this feeling in 2008 or, if relevant, 2012:

Well, there are political families, and there are political families. There's something more than a little off about talking about the Adamses and the Roosevelts in the same breath as the Bushes and the Clintons. And the Kennedys -- well, the gifts didn't survive in the second generation, now did they?

I wouldn't not vote for HRC, or Jeb, because of family connections, but I've got to admit that the idea of spending four more years with either a Bush or a Clinton is depressing.
