Donald Trump leads Marco Rubio 40-24 percent in Florida, according to a new CNN/ORC poll. They lead Ted Cruz, who drew 19 percent, and John Kasich, who drew 5 percent.
Sixty-six percent of respondents said Rubio should drop out if he loses Florida.
The poll had a relatively small sample size -- only 313 Republican respondents -- and an error margin of 5.5 percentage points. CNN's story on the poll doesn't outline its methodology, but it seems likely -- given the poll's wide margin -- that ORC relies on self-identified Republican voters, a method that tends to include independents who cannot vote in Florida's close primary.
