The latest Rasmussen poll gives Rubio an 11-point lead over his nearest challenger. Crist’s lead is the least solidified:

Eighty percent (80%) of Rubio voters now say they are certain how they will vote in November, as do 69% of Meek’s supporters, up from 48% in the previous survey. Only 45% of Crist’s voters say they’re sure at this point how they’ll vote on Election Day. This number bears watching because it suggests the race could follow the typical pattern of three-way contests with voters shifting to one of the two major party candidates.
