Rep. Jim Matheson is one of only eleven House Democrats who continue to publicly oppose legalizing gay marriage, reports The Hill.

Eleven House Democrats are on record as opposing gay marriage, even as support within their party for the issue builds.

Another nine haven’t taken definitive positions in support of or against gay marriage.

President Obama, former Secretary of State Hillary Clinton and a number of Democratic senators have flipped on the issue, and a majority of voters support gay marriage according to polls.

But the issue remains politically thorny, and even in the relatively liberal House Democratic conference there are pockets of opposition to same-sex marriage.
