A majority of voters don't care where a candidate stands on the issue of gay marriage. But of those who do care, more say supporting marriage equality is more likely to influence their vote.

According to an NBC/Wall Street Journal poll released on Monday (as reported by ThinkProgress.com), support for legalizing gay nuptials has grown 8 percentage points since the poll's October 2009 survey. Nearly half of respondents (49%) said they favor legalizing gay marriage, while 40 percent said they oppose it. The number of respondents who said they “strongly oppose” such unions has dropped 20 points since 2004, when 62 percent said they opposed gay marriage and 51 percent said they “strongly oppose” such unions.

A majority (54%) said a candidate's position on the issue would not influence their vote. However, of those who said it was important, 25 percent said they were more likely to vote for a supporter of gay marriage, while 20 percent said they were more likely to vote for an opponent of the institution.

Pollsters contacted 800 adults nationwide from Wednesday through Saturday. Voters in 10 states head to the polls on Tuesday.
