At least Scott's numbers are improving...
This is definitely a winnable race for Scott, even against Crist. Though I agree with Maxwell that this will essentially be a race to the bottom. Personally, if I were in the Scott campaign, I would encourage Scott to start attacking Crist early and often, in the hopes of possibly getting Crist out in the primary (which is entirely possible, assuming a majority of Florida Democrats have actual principles and aren't willing to throw themselves at any candidate just to win).
I also agree with this. While Scott has a hard climb ahead of him, I know for a fact that he will get the most competent young strategists in the state on board his campaign. Not to mention the money factor, which he has a good edge in.
