Bob Buckhorn has always been pro-gay rights, which is why it's not surprising that he'll be riding in a convertible at St. Pete Pride's Carnivale Parade this Saturday.

On the eve of the U.S. Supreme Court's decision on two gay marriage cases, I asked the longtime Democrat if he has come to a decision on same-sex marriage, which he has never taken a formal stance on.

"What I have been asked historically is 'will I join Mayors for Equality?' (the actual name is Mayors for the Freedom to Marry), and I just don't join those national groups," he said on Monday morning. However, he didn't indicate any objections to the idea.

"I am far more libertarian the older I get and so for me, what people want to do is their own business. I'm fine," he added.
