(CNN) - Independent Florida Senate candidate Charlie Crist scored an endorsement from a big Democratic name on Wednesday, as a new poll shows he needs all the help he can get.
Environmental activist Robert F. Kennedy, Jr., the nephew of former President John F. Kennedy and the late Sen. Ted Kennedy, has thrown his family name behind Crist, who until earlier this year held elected office as a Republican.
On Tuesday, the out-going Republican governor of California, Arnold Schwarzenegger, posted his endorsement of Crist on Twitter.
"Our country needs someone like him in DC right now," he wrote.
Meanwhile on Wednesday, a prospective GOP presidential candidate, Louisiana Gov. Bobby Jindal, joined Crist's Republican challenger Marco Rubio on the campaign trail.
A Quinnipiac University poll released Wednesday indicates Rubio has stayed in control of the race over the last two weeks. Rubio holds a 44 to 30 point lead over Crist among likely voters, with the Democratic candidate, Rep. Kendrick Meek trailing behind at 22 points.
The same poll taken two weeks prior had Rubio leading Crist 46 to 33 points, with Meek at 18 percent.
Wednesday's poll was conducted by phone with 1,055 likely Florida voters from Oct. 6-10. It carries a sampling error of plus or minus three percentage points.
