Former House Speaker Newt Gingrich continues towith a new ad deeming frontrunner Mitt Romney's proposals "timid."
"Romney's economic plan? Timid," a narrator says as the spot opens, as a blurry image of Romney appears onscreen. "Parts of it virtually identical to Obama's failed policy. Timid won't create jobs, and timid certainly won't defeat Barack Obama."
The narrator then goes on to deem Gingrich's jobs plan "powerful" and cast Gingrich as a "bold" conservative leader.
The Gingrich campaign said the spot starts airing in New Hampshire and South Carolina tonight. It said the ad buy is "significant," but would not disclose the dollar amount.
Gingrich, who, is promising "a much clearer and sharper contrast" with the former Massachusetts governor in the wake of Gingrich's disappointing fourth-place finish in the Iowa caucuses. Echoing some of his rivals, he says there is a difference between attacking and showing contrasts.
"The most we're going to do is draw a direct and sharp contrast with Governor Romney, who is a Massachusetts moderate, and contrast my fighting against tax increases and his tax increases, or contrast my very bold plan for jobs and economic growth, which The Wall Street Journal Saturday said was the best and most aggressive job-producing plan, with what they characterize as a plan for -- by Romney so timid that it resembles Obama," he said on Fox News Wednesday. He then vowed not to "go into attack commercials and the kind of the negative baloney that some of these guys do."
"In terms of beating Obama, having a clearly defined conservative is vastly more likely to win than having somebody who's confused," he said in New Hampshire Wednesday, in a shot at Romney.
"I'm not in any way confused about my beliefs," he added.
