One-third of Virginia's Republican voters will not vote for Donald Trump should he become their party's general election nominee, according to a new poll.

Sixty-seven percent of Republicans said they would support Trump in November if he emerges as the nominee in July, according to a new Christopher Newport University poll released Thursday. This is a stark contrast to Democrats and their support for front-runner Hillary Clinton — 90 percent of voters said they would support her as their party's nominee in the general election.

If Trump is the nominee, 29 percent of Republican primary voters said they will either vote for the other party's candidate, vote for a third-party candidate or not vote at all. Only 9 percent of Democratic voters said the same should Clinton be the nominee.

In a hypothetical general election matchup between Trump and Clinton, the former secretary of state would win 44-35, the poll said. Virginia is a key swing state with 13 Electoral College votes, and President Obama won the state in 2008 and 2012.

The poll of 1,167 registered Virginia voters was conducted between March 23-April 3 and carries an overall margin of error of plus or minus 3.1 percentage points. For the Republican and Democratic subsets, the margin of error was not disclosed.
