I think the whole dynamic is different. Whereas in [Barack] Obama's case, even though there was no incumbent, he was able to run against eight years of Bush-Cheney and a Republican Congress, and everyone was tired of everything. He was able to benefit from that.
I think that's what's - one of the things that is alarming to me is [Donald] Trump, and I think Trump supporters seem to believe, he won, huge upset, full credit to him, and has got the wind at his back. And Republicans on The Hill do want him to succeed, obviously, and they're deferring to him more than they deep down in private sort of wish - want to, but they are going to defer to him publicly for awhile. But I think that is going to run out faster than people think.
In any case, open-seat presidential elections like 2008 just are different in character from incumbent reelects, and I think that's the most important thing about this election - is that once there's an incumbent running for reelection, most of the debate is about, "Has he [Barack Obama] done a good job?" Most of the judgment is, "Do you want to keep him or do you want to replace him?" Now, the opponent has to also be acceptable and has to make his own case.
I like [ Rick] Santorum personally and respect him, but you wouldn't say that he was really that strong of an opponent. At the end of the day it wasn't like [Ronald] Reagan running against [George] Bush, or [George W.] Bush against [John] McCain, even. It's sort of surprising that Romney had as much trouble as he did, and I think it shows a weakness in appeal to those voters.
