Hillary Clinton has regained her edge in Florida just one month after her Republican opponent swung to a 3-point lead in the crucial battleground state, according to a new Monmouth University poll.

The Democratic presidential nominee leads Donald Trump 48 to 39 percent among voters likely to participate in the November election, with Libertarian Gary Johnson garnering 6 percent support and Green Party candidate Jill Stein drawing 5 percent.

Clinton's momentum comes from a surge in support among independents and non-white voters in the Sunshine State. The former secretary of state carries a 17-point lead over Trump among independent voters, and a 50-point among Hispanic, black and Asian voters — 69 to 19 percent.

Trump continues to best Clinton among white voters (51 to 37 percent), but his lead is narrower than the 24-point edge Mitt Romney carried against President Obama in 2012. The Republican presidential hopeful has opened up a greater gap between him and Clinton among white male voters, but is polling far worse among white women in comparison to Romney.

Fewer than 40 percent of voters view Trump or Clinton favorably, with 50 percent viewing the former first lady unfavorably and 54 percent holding a negative view of Trump. Nevertheless, voters trust Clinton slightly more than Trump when it comes to handling key issues like the economy (49 to 46 percent) and domestic terrorism (48 to 45 percent).

In Florida's Senate race, incumbent Republican Marco Rubio carries a 5-point lead over Patrick Murphy and an 11-point lead over Alan Grayson, both of whom are Democratic members of Congress hoping to challenge the ex-White House hopeful.

While Rubio maintains a net-positive job approval rating and is viewed favorably by 44 percent of Floridians, far more voters (53 percent) said his decision to seek re-election was centered more on a future presidential bid than a desire to serve his constituents (25 percent).

The poll of 402 likely general election voters in Florida was conducted Aug. 12-15. Results contain a margin of error plus or minus 4.9 percentage points.
