- Ninety percent of Virginia Democrats polled said they would support Democratic front-runner Hillary Clinton
The poll, conducted by the Wason Center for Public Policy, showed roughly 30% of likely Republican voters in Virginia are unsure whether they would vote for GOP front-runner Donald Trump in the general election if he is their party's nominee.
In contrast, 90% of Virginia Democrats polled said they would support Democratic front-runner Hillary Clinton in the general election, even if they are currently Bernie Sanders supporters.
In a general election match-up in the state, Clinton leads Trump 44% to 35%.
Trump -- who has long led in GOP national polls -- is under increased pressure to clinch the nomination, following a series of campaign missteps
, and a loss in the Wisconsin primary, increasing the likelihood of a contested convention in Cleveland.
The poll, which surveyed voters who participated in the state's March 1 primary, comes after the two front-runners lost Tuesday's Wisconsin contest
to Texas Sen. Ted Cruz and Vermont Sen. Bernie Sanders. Virginia is likely to play the role of a swing state in November.
The poll surveyed 1,167 registered Virginia voters between March 23-April 3 with a margin of error of plus or minus 3.1 percentage points.
