Romney airs new campaign ad in Iowa

Mitt Romney, in the afterglow of his win in the Iowa straw poll on Saturday, today launched a new television ad that thanks Iowans and casts himself as the agent of change.

"If there's ever been a time that we needed to see change in Washington, it's now," he says in the ad, which excerpts a stump speech. "....Change begins in Iowa and change begins today."

The 30-second ad, which will air in the first caucus state, also quickly hits the high points of his campaign platform in a series of bumper sticker slogans: a stronger military, secure borders, lower taxes.
