Hillary Clinton now has an 6-percentage-point lead nationally ahead of Donald Trump in the 2016 presidential race, according to a Fox News survey released Wednesday.

The poll found Clinton leads Trump 44 percent to 38 percent, which comes after she only had a three-point edge earlier this month. In May, a similar poll found Trump was leading Clinton 45 percent to 42 percent.

In a three-way race involving Libertarian nominee Gary Johnson, Clinton would lead Trump 41 percent to 36 percent and 10 percent would support Johnson.

Support among Republicans for Trump has dropped 8 percentage points, with about three-quarters of Republicans backing him now, down from 82 percent in May.

More than 80 percent of Democrats said they support Clinton and two-thirds of Democrats who preferred Bernie Sanders for the Democratic nomination said they will vote for Clinton.

Clinton leads Trump among black voters, people earning less than $50,000 annually, women and people under the age of 45. Trump, on the other hand, leads among white evangelical Christians, gun owners, men, white voters, independents and white voters without college degrees.

The poll surveyed 1,017 registered voters between June 26 and 28 with a margin of error of 3 percentage points.
