Cheney supports gay marriage?

It's being widely reported that former VP Dick Cheney actually supports gay marriage. Cheney says,

"People ought to be free to enter into any kind of union they wish, any kind of arrangement they wish."

He did say that he opposes any federal regulation, preferring it to be left to the states. Only he didn't actually SAY the word marriage, so I'm not so willing to assume he's had a real epiphany.
