"I think we've got a lot of governors, a number of Republican governors," McCain said. "I like Chris Christie, I like Bobby Jindal, I like … I like a number of those people. They've succeeded in states that have both Republican and Democrat."

"I think we're going to have a very spirited--in the Republican Party, we're going to have a group of people who frankly are isolationists, and there's an international wing," he continued. "I think it's going to be a very interesting debate." Meghan McCain, for her part, was undecided.

Leno later asked the pair to weigh in on Liz Cheney's abrupt announcement that she was dropping out of the Republican primary for a Wyoming Senate seat.

"When you're in a political family, I always say it's kind of like being in a mafia family," Meghan McCain said. "You're the only ones who really know what goes on in the inside. I just think it's sad that two sisters would have their relationship broken up over politics."

Cheney's campaign created a rift in her family when her public position against gay marriage offended her openly gay sister Mary. Her decision to end the campaign, however, stemmed from "serious health issues" within her immediate family.

"I think there was a number of reasons, including that she wasn't doing well in the polls," the elder McCain added. "But I agree with Meghan, there was a great split in the family and it's always unfortunate when that happens."
