Hillary Clinton leads Donald Trump nationally by 6 percentage points, according to a Bloomberg Politics poll released Wednesday.

The survey found that among registered voters, Clinton leads Trump in a two-way race 50 percent to 44 percent.

In a four-way race involving third-party candidates, Clinton would lead Trump 44 percent to 40 percent, Libertarian nominee Gary Johnson would receive 9 percent support and Green Party candidate Jill Stein would get 4 percent.

Ninety-four percent of Democrats said they support Clinton, including a whopping 93 percent of people who supported Sen. Bernie Sanders, I-Vermont, in the primary. The poll found 87 percent of Republicans back Trump. Forty-eight percent of independent voters said they would support Clinton and 41 percent said they'd back Trump.

Clinton has a strong advantage, the poll found, from women, college-educated voters, unmarried voters, people under the age of 35, non-white voters and people who live in the Northeast. Trump, by contrast, has an advantage with men who have no college degree, non-college educated, men, evangelicals, married people and people who live in the South, the poll found.

More than three-quarters of likely voters said they have made up their minds about whom to support in November's election. The poll found that 56 percent said that their decision to vote for Clinton is more of an act to support her than to stop Trump, but 56 percent of people who said they'd vote for Trump said it's more of a vote against Clinton.

Forty-six percent of people under the age of 35 said they will definitely vote in November, which is down from 60 percent in June. The poll found that more than half of Clinton's younger supporters said they are really casting a vote for her in order to prevent Trump from winning the presidency.

More than two-thirds said the U.S. is headed in the wrong direction, with half pointing the finger at Democrats and nearly a quarter blaming Republicans. Nearly a third said they aren't sure who is to blame.

This poll comes after a slew of other national presidential polls showing that Clinton has expanded her lead over Trump.

The poll surveyed 1,007 adults between August 5 and 8 with a 3.6 percentage point margin of error among likely voters.
