Hillary Clinton is edging Donald Trump among Florida likely voters, according to a University of North Florida poll released Thursday, more good news for the former Secretary of State as Democrats are also cheering strong early-voting numbers across one of the nation’s most important swing states.

The poll of 836 likely voters, however, gives one down-ballot Republican good news of his own: U.S. Sen. Marco Rubio leads U.S. Rep. Patrick Murphy by a 6-point margin.

Clinton leads Trump by four points — 43 percent to 39 percent — which is just outside the poll’s 3.39 percent margin of error. Third party candidates Gary Johnson and Jill Stein garnered 6 percent and 3 percent support respectively.

The margin is tighter in a two-way match up: 46 percent back Clinton, and 44 percent back Trump.

"(I)n this election Democrats are outperforming their historical norms in absentee and early voting. If this trend continues through Election Day, Clinton could expand this margin and easily win Florida," said Michael Binder, a UNF political science professor and director of the school’s Public Opinion Research Lab, which conducted the poll.

The survey was conducted Oct. 20-25.

Rubio’s lead, 49 percent to 43 percent, is unmoved from UNF’s last survey earlier in October.

"Rubio can attribute his lead to support from NPAs and more Democrats willing to cast a ballot for him than Republicans are for Murphy," Binder said.

Voters appear also appear likely to approve Constitutional Amendment 2 on the Nov. 8 ballot, which would legalize medical marijuana use in limited circumstances. Seventy-three percent of voters say they will vote "yes," which is far above the 60 percent support required for passage.
