(CNN) – A new poll in Florida suggests Gov. Charlie Crist is maintaining his lead over Republican Marco Rubio and either Democratic candidate in the battle for that state’s Senate seat less than three months before Election Day.
The Quinnipiac University survey shows Crist, who is running as an independent, leading Rubio by a 39-32 percent margin. Rep. Kendrick Meek, who is currently in a primary contest with businessman Jeff Greene for the Democratic nomination, registers 16 percent in the poll.
If Greene should prevail in the Democratic primary, he wins 15 percent of support in a general election matchup with Crist at 40 percent and Rubio at 32 percent, the poll shows.
Listen as CNN's Dick Uliano and Senior Political Editor Mark Preston discuss why Republicans are spending a fortune on a Florida Senate race.

In a matchup against Rubio and Meek, Crist wins support from 45 percent of Democrats, 9 points more than Meek, and 50 percent of the independent voters. Facing Greene, Crist wins 51 percent of the Democratic vote - while Greene gets just 31 percent - and 48 percent of independent voters.
In the governor’s race, Democrat Alex Sink, the state’s chief financial officer who does not have a primary challenge, narrowly leads both Republican Attorney Gen. Bill McCollum by a 31-29 percent margin and businessman Rick Scott by a 33-29 percent margin. In both matchups, independent candidate Bud Chiles is the choice of 12 percent and 20 percent remain undecided.
Republicans McCollum and Scott are currently in a heated primary battle for the GOP nomination.
The poll was conducted on August 11-16 and surveyed 1,096 likely Florida voters. It carries a sampling error of plus or minus 3 percentage points.
