Dubya's campaign was way too moderate to be compared to Perry, and no relation at all to Paul.
George ("Humble foreign policy") Bush was very moderate in the 2000 campaign, and I agree that he doesn't really compare to Ron Paul. Paul is a purist. He wants to start dismantling large apparati of the government, and I'm not sure anyone can be compared to him from 2000.
McCain was a serious neocon. Nuke 'em all/let God sort 'em out. Big on sanctions against Iraq and defense in general. Consistent. He also didn't kowtow to the Liberty University crowd. Is there anyone like McCain this year? I don't think so. Then again, the picture is so different now that no comparisons are apt. Iraq doesn't even exist anymore, for example, mainly due to the not-so-humble foreign policy that George Bush pursued once he was elected.
Hatch was a smooth talker. He was the anti-terrorist point man from the late 90s, and that was a large part of his campaign. He was much more serious than Bush about such things. Maybe Santorum is a bit like Hatch in that regard, but Hatch at least had a sense of humor. Also, Santorum also has a little of the Gary Bauer in him. It's difficult to make on-to-one mappings for these candidates.
