Rick Santorum believes it would be suicidal for the Republican Party to endorse gay marriage.

The 54-year-old Santorum, who lost the 2012 Republican presidential nomination to Mitt Romney, also predicted that the Supreme Court would rule against gay marriage in two cases.

“I'm sure you could go back and read stories, oh, you know, 'The Republican Party's going to change. This is the future.' Obviously that didn't happen,” Santorum told the Des Moines Register. “I think you're going to see the same stories written now and it's not going to happen. The Republican Party's not going to change on this issue. In my opinion, it would be suicidal if it did.”

Santorum also weighed in on two cases related to marriage equality currently before the Supreme Court.

“I think you'll see, hopefully, a chastened Supreme Court is not going to make the same mistake in the [current] cases as they did in Roe v. Wade. I'm hopeful the Supreme Court learned its lesson about trying to predict where the American public is going on issues and trying to find rights in the Constitution that sit with the fancy of the day.”
