Presidential Campaign

Sen. John McCain (R-Ariz.) released a new radio ad Wednesday to air in New Hampshire highlighting his long-held stance that global warming is a problem government should deal with.

McCain, who has led congressional efforts to fight global warming in the past, says he has listened to New Hampshire voters on the issue.

"Not everyone heard you, but I did," McCain says in the ad. McCain emphasizes global warming as a national security issue as well as an environmental one in the 60-second radio spot.

In January McCain reintroduced climate legislation with Sen. Joe Lieberman (I-Conn.), with Democratic presidential hopeful Sen. Barack Obama (Ill.) as an initial cosponsor.

Hillary Clinton takes a direct shot at Republican attacks against her in the campaign's latest ad.

In this Thanksgiving TV ad former Sen. John Edwards (D-N.C.) tells viewers that he is thankful for his parents, his children, 30 years with his wife, 231 years of America, the nation's hopes, and his supporters.

Joseph Ward of Lisbon, N.Y. says that Sen. Hillary Rodham Clinton (D-N.Y.) got a hospital to absorb the cost of his son's bone marrow transplant when insurance would not cover it.

This ad featuring Ward, Clinton's latest TV ad of the '08 race, is her second focusing solely on healthcare, a major issue in Clinton's campaign. Clinton released her first healthcare ad in September to outline her plan for universal healthcare; click here to see it.

Former Arkansas Gov. Mike Huckabee (R) will begin airing a TV ad in Iowa Monday featuring Chuck Norris, the action star who endorsed Huckabee for president Oct. 21. In it, Huckabee and Norris take turns listing facts about each other.

Huckabee claims Chuck Norris is his plan to secure the border. He also says that Norris "doesn't endorse -- he tells America how it's gonna be."

Staff Writer Sam Youngman talks to Congress Blog Editor Andy Barr about the Democratic debate tonight in Las Vegas and recent news from the campaign trail.

Former President Bill Clinton runs on a treadmill while watching a fast food commercial, former Iowa Gov. Tom Vilsack (D) dances feebly with his wife, and Sen. Hillary Rodham Clinton (D-N.Y.) sings the national anthem grossly off-key in this Clinton web ad telling Iowans that "caucusing is easy."

A narrator tells viewers that "exercising is hard," "dancing is hard," and "singing is hard" before informing them of the ease of caucusing Jan. 3, 2008 in Iowa.

Fred Thompson goes back the small town diner for his 2nd TV ad that began airing in Iowa today. The ad lays out Thompson's policy on immigration, which the ad boils down to 3 phrases that appear on the screen "secure our borders," "enforce the law" and "no amnesty."

Former New York City Mayor Rudy Giuliani surprisingly does makes no mention of his response to Spetember 11, a major campaign theme for Giuliani, in his first TV ad that will begin airing in New Hampshire on Thursday. In the ad, titled "tested," Giuliani takes credit for the economic turnaround in New York and highlights his leadership of a large "unmanageable" city.

Former Senator John Edwards starts running the first South Carolina ad from a Democratic hopeful today. The ad shows Edwards at the now closed mill where his father worked for 30 years. "For too many it's just about profits and greed," Edwards says. "They're wrong. It's about the dignity of a job and doing what is right for American workers." Edwards has made several pleas to labor groups, but has lost out on many major labor endorsements.
