John McCain re-elected to Senate in Arizona

John McCain has been re-elected to a sixth term in the U.S. Senate, defeating Rep. Ann Kirkpatrick in Arizona by a wide margin.

McCain's victory doesn't come as a surprise, however, since the most recent Real Clear Politics average poll showed him leading by ten points.

The Arizona Republican faced one of toughest primaries of his career this election cycle, although he still beat GOP challenger Kelli Ward by more than 12 points. Ward made headlines late in the primary campaign by suggesting that McCain was too old to seek re-election.

Ward said in August that, as a physician, she knows "what happens to the body and the mind at the end of life," further referring to McCain, who turned 80 this year, as "weak" and "old," the Arizona Republic reported.

“The life expectancy of the American male is not 86. It’s less," Ward told Politico, referring to the six-year term to which McCain was re-elected.
