As voters discover the truth about the kind of business Romney practiced, the candidate is finding out that coming to town now means bad news for his popularity. The more voters learn about him, the less they like him. It's not hard to see why.
The Republican race is now a true two-man contest between Newt and Mitt. In fact, if Newt wins Florida, he may have built up so much momentum that people start using the word "inevitable" to describe his nomination, rather than Mitt's.
If Romney doesn't perform better in the debates and change the national momentum that is in Gingrich's favor at this point, then the endorsements, television ads, and organization he has in Florida won't matter. Romney needs to move the nation before he can move Florida.
