A new poll shows a majority of voters in Virginia oppose the state's ban on gay marriage.

According to a Christopher Newport University poll of 944 registered voters, including 753 likely voters, conducted last week, 56 percent of respondents oppose Virginia's 2006 constitutional amendment which prohibits the state from recognizing any union other than a heterosexual marriage, while just over a third (36%) support the ban. Seven percent refused to answer.

“Three in four Democrats oppose the ban, while nearly six in ten independents oppose it,” pollsters said in announcing their findings. “Among Republicans, 60% support the ban.”

Voters overwhelmingly (57-43%) approved the ban in 2006.

Two lawsuits challenging the constitutionality of the law have been filed in recent months. Lawyer Ted Olson and David Boies, who represented two gay couples in the fight to end California's marriage ban, Proposition 8, last month joined one of the Virginia lawsuits.
