McCain's primary opponent: He's gotten weak and old, could die in office

“So you think he’s too old to serve in the Senate?” host Chuck Todd asked.

“I think anybody who’s been in Washington for almost 40 years has been there too long,” Ward said.

“But you brought up his age. That’s a tough attack,” Todd said.

“Well, I’m a physician,” she said. “I see the physiological changes that happen in normal aging in patients again and again and again over the last 20, 25 years, so I do know what happens to the body and the mind at the end of life.”

“You feel comfortable diagnosing him on air like this?” Todd asked.

“Diagnosing him as an 80-year-old man? Yes, I do,” Ward said.
