Thanks Freedom for the clip. This question was asked of Cheney back in 2000 and that is what he said back when he was running for VP. So, the first major party ticket member to support us was a Republican. Long before any major Democrat did. While I think the Republican Party has been incredibly wrong on this issue, demonizing the entirety of Republicans is both wrong and counterproductive.
Personally, while I'm not a Republican, much of my family is and all of them supported gay marriage long before any major Democrat did. On the other side, almost none of the Democrats in my family supported gay marriage until recently.
And, this support wasn't because of me. My mom first voiced support over twenty years ago before she knew I was gay.
