Bill Nelson has a nominal lead over Gov. Rick Scott in a hypothetical U.S. Senate matchup, according to a new poll that shows a large number of undecided voters. The race for governor is similarly unsettled.

President Donald Trump has a 37 percent approval rating, up slightly from his 35 percent approval rating in the Florida Atlantic University June survey.

From the poll:

* Nelson has a slim 42-40 percent lead over Scott, who has set up a political action committee ahead of a likely run for Nelson’s seat, which he has held since 2001.

Our poll found younger voters 18 to 34 years old are more likely to vote for Scott, while voters 55 and over favor Nelson,” said Monica Escaleras, Ph.D., director of the BEPI. “It will be interesting to see what the candidates do to try to draw support from each of those generations.”

* A majority of Republicans (53 percent) in the survey said they are undecided on their choice to succeed Scott as governor. Adam Putnam, Florida’s commissioner of agriculture, has distanced himself from the rest of the GOP field, with 27 percent of those surveyed supporting him, compared to 10 percent for House Speaker Richard Corcoran, 9 percent for Congressman Ron DeSantis and just 2 percent for Jack Latvala, a member of the Florida Senate.

* The race is wide open among Democrats, with activist and attorney John Morgan leading with 19 percent, compared to 14 percent for former U.S. Congresswoman Gwen Graham, 9 percent for Tallahassee mayor Andrew Gillum and 8 percent for Miami Beach Mayor Philip Levine. Over 47 percent of Democratic voters polled are undecided.

* Voters also were asked about current issues in the news. Nearly half of the respondents (49 percent) said that statues honoring leaders of the Confederacy should remain in public places, while 30 percent said they should be removed and 21 percent were unsure.

* Voters were split in their opinions about Trump’s remarks following the events in Charlottesville, Va., that “there is blame on both sides,” with 44 percent disagreeing with the president, 42 percent agreeing with him and 14 percent undecided.

* Asked about what limitations, if any, should be placed on carrying handguns in a public place, 43 percent said Floridians should be allowed to carry a concealed handgun in a public place, as long as they have a license, while 15 percent said they should be allowed to openly carry a handgun in public places with a license. More than one-third of respondents (34 percent) said Floridians should never be allowed to carry a handgun in a public place. Only 7 percent said Floridians should be allowed to carry a handgun in a public place without a license.

* Voters were split on the debate over the future of the Affordable Care Act. While 37 percent said Obamacare should be replaced completely, 33 percent said it should be repealed in part and 30 percent said it should be kept as is.

The poll included 800 registered Florida voters and was taken Aug. 24-26 online and through robocalls.

The survey has a margin of error of +/- 4 percentage points (the margin of error for either the Democratic or Republican primary was +/- 6.5 percentage points). Responses for the entire sample were weighted to reflect the statewide distribution of the Florida population by gender, race/ethnicity, region, education and age according to latest American Community Survey data.
