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.
Does the Florida Democratic Party even have any other credible candidate not name Charlie Crist?
The Florida Democratic Party is one of the worst state parties.
