Minnesota Senator Al Franken says he “completely disagrees” with Minnesota Rep. Michele Bachmann on gay rights, adding that he sees little point in discussing such issues with the presidential candidate.

The 60-year-old Franken also told gay glossy The Advocate that he believes that voters will reject a 2012 ballot measure that seeks to constitutionally ban gay marriage in the state.

“I think we'll win this one, but I think it will be very close. We're a very divided state, and on this issue I don't have the strongest sense on where it's going to be,” Franken said. “I know there are people who just have their views and are against marriage equality.”

When asked about Bachmann, Franken said he liked her, then added: “I just completely disagree with her on this issue [of gay marriage] – and almost everything else.”

Franken also said he had not spoken to Bachmann about the issue of marriage equality.

“I don't think it would accomplish much,” he said. “I'm not going to change her mind. There's a million things I could talk to her about. … When you have an actual issue in which you can get something done, that's the only time you really discuss issues, otherwise it's just, uh, useless.”
