In an appearance Monday night on “The Tonight Show,” host Jay Leno asked McCain whom he would support. 

“I think we’ve got a lot of governors,” he said. “I like Chris Christie. I like Bobby Jindal. I like a number of those people who have succeeded in states that have both Republican and Democrat.”

President Obama defeated McCain, now 77, in 2008 by a margin of 365-173 electoral votes.

“In the Republican Party, we’re going to have a group of people who are frankly isolationist and there’s the international wing. I think it’s going to be a very interesting debate,” McCain added.
