McCain reminds voters of his heroism

John McCain is returning to the roots of his heroic life story to try to revive his flagging presidential bid.

In a new video, "John McCain: Courageous Service," he describes his decorated career as a Navy pilot and the six years he spent as a POW after being shot down over North Vietnam.

"The transcendent issue of the 21st century is the struggle against radical Islamic extremism and I, with considerable ego, say that I'm the best prepared and qualified to meet this challenge," the Arizona senator says in the video.

The 12-minute video was screened Thursday night for supporters at his New Hampshire headquarters in Manchester and is available on his website.

"This video displays the courage and faith John McCain has shown throughout his entire lifetime of service and sacrifice," Peter Spaulding, New Hampshire chairman for McCain, said in a statement issued by the campaign today. "It tells the important story of a man whose courage in the face of adversity and abilities as a leader make him the most prepared candidate to be our next commander-in-chief."

The statement also included this testimonial, from Paul Chevalier, co-chairman of New Hampshire Veterans for McCain: "This film reminds people of John McCain's courage and devotion to his country. Those watching, including myself, were visibly moved by the testimony of family, friends, and the band of brothers who served with him."

Once the front-runner for the Republican nomination, McCain is now third or even fourth in most polls, behind Rudy Giuliani, Fred Thompson, and Mitt Romney. McCain cut his campaign staff after spending most of his campaign war chest and not raising as much as expected.

His campaign announced today that he will return to New Hampshire on Tuesday for events including a student forum at Concord High School and a town hall meeting in Bow.
