McCain the maverick returns in ad

John McCain reverts to his maverick past in a new TV ad that his presidential campaign announced this morning will run in New Hampshire.

The Republican brags about making lots of people in Washington angry -- defense contractors when he pointed out misspending, lobbyists when he co-authored a sweeping campaign finance measure, the Pentagon when he criticized former Defense Secretary Donald Rumsfeld's strategy for not sending a bigger force into Iraq, and his own colleagues when he questioned pork barrel spending. (Watch it here.)

"I didn't go to Washington to win the Mr. Congeniality award," McCain says in the ad, speaking directly to the camera with an austere black background. "I went to Washington to serve my country. I might not like the business as usual crowd in Washington. But I love America. I love her enough to make some people angry."

The Arizona senator ran an insurgent campaign for the Republican nomination in 2000, but became a loyal supporter of the Bush administration until recently. Many of his supporters believe that his maverick style serves him better and broadens his support, especially in New Hampshire, where he is counting on independents choosing to vote for him in the Republican primary Jan. 8.
