Sen. John McCain, Arizona senator – and a Republican In Name Only to tea-party types – is going to face an election year challenge from Kelli Ward, a 46-year-old doctor and second-term Arizona state senator. Hundreds of supporters packed into a Lake Havasu City banquet room to hear her official announcement: “I, Dr. Kelli Ward, a proud mom, a physician, a military wife and yes, I am running for the United States Senate,” Breitbart reported. McCain has been serving in Washington, D.C., since 1983. He faces a re-election battle in 2016.
