Charlie Crist and Gov. Rick Scott are certain to steamroll token opposition in today's gubernatorial primary, but it's not without significance.
Crist should rout former state senator Nan Rich in the Democratic primary, but not every Democrat is gung-ho about a lifelong Republican switched to the Democratic Party just two years ago.
University of South Florida political science professor Dr. Susan MacManus says Crist needs to win big today to present a united Democratic opposition to Scott.
MacManus says Crist needs South Florida Democrats to head the polls in the kind of the numbers they didn't muster in 2010.
Scott, meanwhile, had no real opposition in the Republican primary.
