I'd say that besides the fact that he actually brought the troops home from Iraq (sort of), he's worse than Bush. He's been asking for totalitarian powers that even Bush didn't have, and pretty much everything he promised in the campaign he did the opposite when he got in White House.

As for the Iraq part, well if he starts a war with Iran already, he's really not better than Bush at all. Check out how they want to collapse the Central Bank of Iran in 60-180 days, and also a bit of history between Iran and USA:

Also, even Bush thought bombing Iran would create blowback (which is exactly what Ron Paul has been saying all along):

Also, Bush's foreign policy before he got elected was almost identical to that of Ron Paul, of non-interventionism and not being the world police:
