ESTERO, Fla. - On the heels of a new poll out showing Marco Rubio pulling a head in the Senate race, the Republican hopeful did little to move beyond his stump speech while meeting with a group of supporters on Saturday.

Rubio's warm welcome, however, was briefly interrupted when protesters held up signs criticizing his position on immigration, specifically, Rubio's support of Arizona's controversial immigration law and his opposition to a bill that would have provided a pathway to citizenship for undocumented students who attend college or jointed the military.

Meanwhile, Governor Crist is set to pick up a key endorsement from a Democrat. Former Florida Congressman Robert Wexler will campaign with Crist on Sunday in South Florida.

Crist, who running as an independent, stands to benefit from as much Democratic support as he can get in the three-way race.

Former Vice President Al Gore is also getting back on the campaign trail in the Sunshine state. He'll stump for Democrat Kendrick Meek next week with a stop in Tampa.
