"A trio of Republican presidential candidates have signed a pledge promising to oppose same-sex marriage if elected to the White House and to establish a presidential commission to 'investigate harassment of traditional marriage supporters.' The three GOP candidates — former Massachusetts Gov. Mitt Romney, U.S. Rep. Michele Bachmann (R-Minn.) and former U.S. senator from Pennsylvania Rick Santorum — each penned their names to the pledge, which was written by the anti-gay National Organization for Marriage."
I could not vote for someone who doesn't believe in equal rights.
(And no, Santorum and Bachmann are not serious contenders. But Romney is the frontrunner.)
