McCain defeats conservative primary challenger

PHOENIX – Sen. John McCain routed conservative challenger J.D. Hayworth on Tuesday in the Republican primary in what could be the final campaign for the former GOP presidential nominee.

McCain spent more than $20 million to beat back an aggressive challenge from Hayworth, who relentlessly attacked the senator for his shifting stance on immigration and sought to tap into the anti-incumbent rage that has taken down other lawmakers in 2010.

"I will do my best to prove worthy of the honor," McCain told supporters. "I have never and will never take your support for granted, or feel I am entitled to your trust without earning it."
