When you see no one with over 20%, and you see Giuliani in the top three, you know a) it’s way early, and b) it’s mainly a name recognition poll at this point.
granted polls are meaningless at this stage but they do point out trends. And the polls are showing Palin numbers going up, that Palin and Mitt are consistently one and two, and her unfavs going down. the actual % or number isn’t real important.
