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).
The Democratic party has proven itself incapable of such principle.
