(CNN) - Florida Democratic gubernatorial candidate Alex Sink has a slight advantage over her opponent, Republican Rick Scott, according to the latest Quinnipiac University poll.
Sink, the state's chief financial officer, leads 45 percent to 41 percent over Scott, a former health care executive, while 11 percent of likely voters said they are still undecided in the October survey. Sink's four point advantage is within the poll's sampling error.
Nine percent of those who named a candidate said they might still change their mind, underscoring the precariousness of the hotly contested race just a week before Election Day.
"With one in eight voters still in play and Scott's supporters slightly more solid in support, this race looks like it will go to the finish line as a dead heat," says Peter A. Brown, assistant director of the Quinnipiac University Polling Institute.
A Quinnipiac Poll released in early October indicated that Scott held a 45 to 44 percent lead among likely voters over Sink.
In the state's Senate race, Republican Marco Rubio continues to lead independent Gov. Charlie Crist 42 to 35 percent, while Democratic Rep. Kendrick Meek trailed by 15 percent, according to the poll.
In a Quinnipiac Poll taken on October 13, Rubio got 44 percent of likely voters to Crist's 30 percent. Twenty-two percent of likely voters chose Meek, indicating a sharp decline in support for the Democrat over the last two weeks.
"With his supporters less likely to change their minds than those of his two opponents, Marco Rubio is in the driver's seat with only five days to go until Election Day," Brown said. "Most of the closure came not from Rubio voters deserting him, but from Congressman Kendrick Meek's voters moving to Crist."
Brown also noted that though Rubio's lead has narrowed slightly to Crist, the Republican-turned-independent governor still faces external factors that could work against him on Election Day.
"He is listed at the bottom of the ballot below a number of unknown independent and minor party candidates. And, since he is without a party, he lacks the ground operation that the Democrats and Republicans have to turn out their voters," Brown said.
The Quinnipiac University poll was conducted from October 18-24, and surveyed 784 likely voters by live interviewers. The poll has a margin of error of +/- 3.5 percentage points.
