Washington (CNN) - The man who wants to oust Sen. John McCain, R-Arizona, is so worried about states allowing same-sex marriage, he fears it'll lead to bestiality.

At least that is what former Rep. J.D. Hayworth, R-Arizona, intimated Sunday in an interview with Orlando, Florida radio station WORL when discussing the decision in Massachusetts to recognize gay marriage.

"You see, the Massachusetts Supreme Court, when it started this move toward same-sex marriage, actually defined marriage," Hayworth said. "Now get this, it defined marriage as simply, quote, 'the establishment of intimacy.' Now how dangerous is that?"

Hayworth continued, "I mean, I don't mean to be absurd about it. But I guess I can make the point of absurdity with an absurd point. I guess that would mean if you really had affection for your horse, I guess you could marry your horse."
