Not that she’s exactly shown herself to be gay friendly so far, but US vice presidential nominee Sarah Palin has confirmed her support for a constitutional ban on gay marriage.

In an interview with the Christian Broadcasting Network, Palin says she’s voted – with what she says is - "the vast majority of Alaskans" who had the opportunity to vote to amend the US Constitution defining marriage as between one man and one woman in 1998.

"I wish on a federal level that that's where we would go because I don't support gay marriage," Palin said.

"I’m not going to be up there judging individuals sitting in a seat of judgement telling them what they can and can’t do, but I can express my opinion and take actions that I believe would be best for traditional marriage,"

"And that’s casting my votes and speaking up for traditional marriage."

The claim puts her at slight odds with her running mate John McCain, who has said he is happy with letting individual states decide on the issue and has spoken out against a federal marriage amendment.

He has however supported a ballot initiative in Arizona that would ban gay marriage there.

The full interview with Palin will be broadcast on CBN today.
