Hillary Clinton has a sizable lead over Donald Trump in the critical swing state of Florida, according to a new poll released Tuesday, but so far the controversial GOP nominee isn’t dragging down Sen. Marco Rubio with him.

A poll released by Monmouth University showed Clinton leading Trump by nine percentage points in the Sunshine State, 48-39. Voters have a similarly negative view of both Trump and Clinton – 50 percent see the Democratic nominee unfavorably while 54 percent have an unfavorable opinion of the GOP nominee. But by a small margin, they said Clinton is more able to handle the economy and terrorism than her Republican opponent.

Despite the widening lead in the presidential race, Rubio remains in a strong position over both of his potential opponents in the Senate election.

Rubio leads Rep. Patrick Murphy by five points, and Rep. Alan Grayson by 11, according to the Monmouth poll. (The primary between Murphy and Grayson is set for the end of this month, and Rubio faces his own primary challenge from Republican businessman Carlos Beruff.)

Rubio, like other Republican senators running for re-election this year, has struggled with how to handle having Trump atop the ticket, particularly given the harsh attacks the two traded when Rubio was running for the GOP nomination. During the presidential primary, Rubio called Trump a “con man” and said he can’t be trusted with the nuclear codes. In an interview with the Miami Herald this week, he said he stands by those attacks, but still supports Trump.

“We’re in a different place now,” he said. “Now we have a binary choice — not a choice between 15 people or 12 people. There are two people in the world that are going to be the next president, either Donald or Hillary.”

Despite Democrats’ relentless criticism of Rubio’s position on Trump, so far it isn’t causing him significant damage with voters. Less than half of the poll respondents knew that Rubio had endorsed Trump for president.

Just 4 percent of Republicans said Rubio’s endorsement of Trump made them less likely to vote for him, while 18 percent said it made them more likely to support the senator. But his backing of Trump might cause a problem with independents, 28 percent of whom said backing the business mogul made them less likely to vote for Rubio.

While Rubio has maintained a narrow lead over Murphy, who is considered the frontrunner in this month’s primary, there were positive signs for the Democratic congressman. He’s within the poll’s margin of error, and while both Rubio and Murphy have positive favorability ratings among Florida voters, 68 percent have no opinion of Murphy compared to 27 percent for Rubio, showing the Democratic challenger has room to increase his support.

The poll, conducted Aug. 12-15, surveyed 402 likely voters and has a margin of error of plus or minus 4.9 percentage points.
