Did you even bother to read the article?
Reid said Allen believes the Defense of Marriage Act, which Congress passed in 1996, is sufficient to protect the institution of marriage in the United States. The act, known as DOMA, defines marriage under federal law as a union between a man and a woman and declares that no state can be forced to recognize same-sex marriages performed in another state.
“He would only support a constitutional amendment if it becomes absolutely necessary,” said Reid. Right now, Allen believes DOMA “has already resolved this issue,” Reid said.
What you people have yet to learn about Allen is that he will not vote the party line just because it's the party line. He will think though and read up on each issue before making a decision.
What you also have to understand is that he's not about pushing or supporting legislation just because. He has to believe that it's actually necessary. He won't support a law just because it's ~there~.
THAT's conservatism. THATS's limited government.
What year was that article? It's important to note that Allen has since realized that DOMA hasn't resolved the issue and is now a cosponsor of the Federal Marriage Amendment (FMA).
“I believe strongly that marriage is the union of one man and one woman. That is why I am a cosponsor of a Marriage Amendment to the Constitution to protect the institution of marriage.” -- George Allen
