She noted that her husband didn't shy away from a political fight but emphasized that it was never personal, pointing to his interactions with former Sen. Ted Kennedy (D-Mass.).

“It was never personal with him,” she said. “He and Ted Kennedy used to fight like cats and dogs on the floor, but they were the best of friends. ... I wish we could go back to that.”

McCain also said that if her husband were still alive he'd be right in the mix saying, "No, we’re going to work together.”
