The latest poll in the U.S. Senate race in Florida gives Gov. Rick Scott a slim lead in the contest and further underscores the closeness of the race between Scott and incumbent Democrat Bill Nelson.

The Axios/SurveyMonkey online poll shows Scott holding a 3-point advantage over Nelson — 49 percent to 46 percent, with 5 percent has Republican Gov. Rick Scott with a 3-point edge over Democratic Sen. Bill Nelson, 49-46 percent, with 5 percent giving no answer.

The Florida poll was one of a series conducted by Axios/Survey Monkey involving Senate races  showing Democrats will have a tough time taking control of the Senate come November.

The map remains a major obstacle to the Democrat’s quest to flip control of the U.S. Senate. Though they can attain a majority with a net pickup of just two seats, their defense of 10 incumbents seeking reelection in states carried by Donald Trump in 2016 remains their critical challenge, according to the SurveyMonkey’s latest round of state polls conducted for Axios.

The Florida poll also shows voters closely divided regarding President Donald Trump’s approval rating. Fifty percent of the voters surveyed approved of the job the  president is doing, while 49 percent disapprove.

Voters were equally divided when it comes to Nelson’s job performance in the Senate. Forty-seven approved while 47 percent disapproved, 6 percent didn’t have an opinion.

Sen. Marco Rubio did better when it comes to job performance with 52 percent approving of the Republican senator, while 47 percent disapprove.

Asked about the issues most important to voters, 23 percent said jobs and the economy, 19 percent said health care, with 18 percent saying immigration.

There is some good news for Democrats in the poll. It shows that Democrats do have a slight edge in enthusiasm. Fifty-three percent registered Democrats and those leaning to that party say  they are enthusiastic about voting in November. That compared to 46 percent of Republicans and those who lean to the GOP.

The poll of 1,080 registered voters in Florida was taken from June 11-July 2. It has a margin of error of +/- 5 percent.
