Looking at exit polls in 2006 and 2010 with comparisons to 2014, it seems that Scott did worse with Latinos in 2014 and did better with AA. In 2010 Scott did better with Whites and worse with women relative to 2014. Crist not being a women like Sink hurt him relative to Sink with respect to the women vote but did gain ground with Whites. Somehow Crist did a lot worse with AA and lost a narrow election. So perhaps Crist not being see as a DINO hurt him with the core Dem vote (AAs) but helped in with the GOP base (Whites).
A lot of Scott's ads had blacks in them......obviously they're in the minority but the fact that they're able to get multiple blacks in an ad for Scott in 2014 says something. The GOP can get 20-25% of the African American male vote in a good election (the female vote is just about monolithically D though).
