Hillary Clinton has opened up a double-digit lead in the key battleground state of Virginia, 55-36, after the two candidates were tied back in May.

The poll by Roanoke College said that in a four-way matchup, Clinton still dominates the Republican nominee by 16 points, 48-32. Libertarian nominee Gary Johnson won 8 percent of likely voters, Green Party candidate Jill Stein had 3 percent and 9 percent remain undecided.

Clinton's favorable ratings, though not good, have improved from May, moving from 35 percent favorable and 50 percent unfavorable to 39-45. Trump's numbers have gotten worse, going from 56 percent unfavorable in May to 63 percent unfavorable in August. His favorable rating has remained the same at 23 percent.

Respondents were also more pleased with the idea of Clinton winning.

Twenty percent said they would feel proud and 32 percent would be satisfied with a Clinton win, but 28 percent said they would be disgusted — numbers that are largely unchanged for the former secretary of state in three months.

However, opinions of a Trump presidency among Virginia voters have gotten worse since May: 7 percent said proud, 27 percent said satisfied and 49 percent said disgusted.

"There is no silver lining in this dark cloud for Donald Trump. His numbers are mostly negative and stagnant," said Dr. Harry Wilson, director of the Roanoke College Institute for Policy and Opinion Research.

The poll of 803 likely voters in Virginia was conducted Aug. 7-17 and carries a margin of error of plus or minus 3.5 percentage points.
