Hillary Clinton holds a 9-percentage-point lead over Donald Trump in Florida, according to a new poll by Monmouth University, which also found Marco Rubio ahead of his two chief rivals for U.S. Senate.
Clinton drew 48 percent support in the poll, compared to Trump's 39 percent. Six percent went to Libertarian Gary Johnson, and 1 percent to Green Party candidate Jill Stein.
Clinton's advantage comes from her backing from Hispanic, black and Asian voters, who favor her over Trump by 65-19 percent. She also bests Trump among white women, by 49-39 percent, though he leads among white voters overall, including both college and non-college graduates. She's got stronger support among Democrats (92 percent) than Trump does among Republicans (79 percent). Independent voters are also leaning toward Clinton, by 47-30 percent.
Most voters still view Clinton and Trump very unfavorably.
"The gender split among white voters in Florida is huge," Patrick Murray, director of the Monmouth University Polling Institute, said in a statement. "Men are drawn to Trump's message while women are not. These offsetting factors give Clinton the edge."
In the Senate race, incumbent Rubio leads U.S. Rep. Patrick Murphy of Jupiter by 48-43 percent and U.S. Rep. Alan Grayson of Orlando by 50-39 percent. Murphy and Grayson are running in the Aug. 30 Democratic primary.
Among poll respondents, 53 percent said they thought Rubio chose to run for re-election to improve his chances to seek the presidency again. Sixty-three percent were unaware Rubio had backed Trump; most respondents didn't care but about 25 percent said the endorsement would make them less likely to vote for Rubio for Senate.
"Rubio's endorsement of Trump could come back to bite him if more voters actually learn about it," Murray said. "It remains to be seen whether the eventual Democratic nominee can turn this to his advantage in the general election campaign."
The telephone poll of 402 likely voters was conducted from Aug. 12-15. It has an error margin if 4.9 percentage points.
