A new poll of Virginia voters gives Democrats the advantage in November's General Assembly races.

The Roanoke College Poll surveyed 556 potential voters in mid-August.

They were asked which party's candidate they would support if the election were held today.

In the generic ballot for the Virginia Senate, 36% said they would vote for the Democratic candidate in their district, while 31% said they would support the Republican candidate.

In the generic ballot for the House of Delegates, 38% said they would vote for the Democratic candidate and 30% said they support the Republican candidate.

"What we're seeing is sort of what we've seen over time, and the trends I think moving in the direction of the Democrats," said Harry Wilson, Director of the Institute for Policy and Opinion Research. "Republicans, I know, are not happy about that, but that's the way things have been going in this state for the past decade probably."

The poll also indicated that support for President Trump has fallen, with 27% of those who took part in the survey saying they approve of the way he is handling the job, down from 38% in February.
