The polls you refer to, are based on old and inaccurate samples. Most internal polling since the debates in SC, and especially after last night, Newt is well established as in the lead. Very similar to SC.
You can expect to see Newt win Florida also. Santorum has no money or organization in Florida either, so his numbers will probably be in the single digits by then.
Romney falls apart when he gets exposed and rattled, especially now, that he is actually being asked some hard questions and the “coronation” has now been scrapped.
I am going on what I've seen. I expect there will be an uptick for Gingrich.
