The interview is here. Some highlights:

know your son was married recently. If your son had been born gay, would you want him to have the same rights that he enjoys today?
I would want him to have the right to have a stable relationship. But whether you call it marriage or not is up to the church or the synagogue or the mosque. And it’s up to the state legislatures. I think marriage is a term of art. It’s a term of usage. But the legal side of it is not: It’s not negotiable.
But about 40% of U.S. marriages every year happen without any religious participation.
I support whatever the state says. If the state of Massachusetts says we’re going to form a civil union but we’re going to call it marriage, then as far as I’m concerned, that’s marriage.
So you support Massachusetts’s calling it marriage?
Yeah, absolutely.
How do you think Congress would react to that?
Well, they’ll love it. This is exactly what they’re looking for. Newt Gingrich [KJL: Why would I even wonder if he knows that Newt isn’t Speaker any more?] and Tom DeLay and all those guys are looking for a real hand grenade to throw into the Democratic Party. It’s an absurd issue, and it’s one of the reasons I’m running. No one can accuse me of being soft on defense, and no one can accuse me of not knowing about what the armed forces are about. And when I say, “It’s OK,” then it’s OK, period. But elections aren’t always about common sense. And I think [Republicans] would love to frighten people.
