I still think Scott stands a decent shot here - he is going to have the financial advantage. Scott is also polling at only 71% with Republicans - once the attacks start on Crist I suspect most will come home to him. And in a "race to the bottom", I think he has a somewhat easy task at destroying Crist's favorably. I would not be surprised to see both under 40% on Election Day.
Financial advantage hasn't done him much good so far. I'd suspect there's a lot of Republicans who are privately backing Charlie - people like Mike Fasano and Paula Dockery come to mind - which could explain the numbers with Republicans. And Crist's favorabilities are a lot more resistant than you give credit for. This is Charlie Crist, after all. The man's the physical embodiment of sunshine. Personable, telegenic, and (as we saw with the Lopez-Cantera interview) funny (or, in other words, the opposite of Scott).
