A new Mason-Dixon poll shows Marco Rubio with a 17-point lead over Charlie Crist. From the Orlando Sentinel:

Rubio is now supported by 45 percent of voters, while Crist gets 28 percent and Meek gets 21 percent. Rubio’s lead is now bigger than ever – virtually insurmountable, according to Mason-Dixon pollster Brad Coker.
“Stick a fork it in,” Coker said, “because it’s done.” In his analysis, Coker wrote, “There is simply no mathematical formula by which Crist or Meek can approach Rubio’s 45 percent support level.”
