Gingrich keeps aim on "timid" Romney

DES MOINES, Iowa - Newt Gingrich blamed a poor showing in the Iowa caucuses on his rivals' attack ads and seemed to conclude that turnabout is fair play as he pressed on with a new aggressive stance against front-runner Mitt Romney, who won the first Republican presidential contest by a narrow 8-vote margin over Rick Santorum.

After criticizing Romney for running a negative campaign and promising to stay positive, Gingrich, who placed 4th in the caucus with 13 percent of the vote, appeared before supporters to criticize the former Massachusetts governor as someone who couldn't bring change to Washington. He also planned to run television ads against Romney in the next three states to vote — New Hampshire, South Carolina and Florida.

The former House speaker called Romney a "Massachusetts moderate who, in fact, is pretty good at managing the decay." He said the ex-governor has "given no evidence in his years in Massachusetts of any ability to change the culture or change the political structure."

Gingrich continued to hammer away at that theme, placing a full-page ad in the Manchester Union Leader Wednesday laying out "The Choice," in which he labeled Romney a "Timid Massachusetts Moderate," while calling himself a "Bold Reagan Conservative."

Gingrich's turnabout in strategy came after slipping from the lead in Iowa polls, which he held just a few weeks ago. Gingrich blamed his fall on attack ads taken out by Romney's Super PAC. Romney has sought to insulate himself from negative ads, prompting Gingrich to call him a liar during an "Early Show" interview Tuesday. (Watch at left.)

Despite the fourth-place finish in Iowa, Gingrich said he does not foresee the GOP race ending anytime soon.

"One of the things that became obvious in the last few weeks in Iowa is that there will be a great debate in the Republican Party before we are ready to have a great debate with Barack Obama," he said.

Gingrich congratulated two other contenders, Rick Santorum and Ron Paul, for strong showings ahead of him but emphasized he will air contrasts between himself and Romney. He praised Santorum, who ran neck and neck with Romney to win the caucuses, for running a "great, positive" campaign. And while he praised Paul, who garnered 21 percent of the vote in Iowa, he warned his foreign policy was dangerous.

Earlier Tuesday, Gingrich vowed to fight on and said the negative ads against him, many run by a political action committee backing Romney, had taken a toll. Gingrich told The Associated Press while grabbing a snack at his hotel coffee shop that he just needed a little more time to reach out to voters and rebuild the lead he once held but that evaporated in a barrage of attack ads.

"We needed two more weeks," he said.

At least one pro-Gingrich super PAC also was getting into the mix.

"We definitely plan to engage," said Rick Tyler, a former longtime Gingrich aide now working for the pro-Gingrich super PAC Winning our Future. "I think that Newt has signaled a communications shift in which he wants to define Romney and to draw a contrast between his record and Romney's."

Tyler declined to be specific about the group's plans. The independent political action committees are banned by law from coordinating with the candidates they are supporting.

A key question is whether Gingrich will have the cash to wage an effective assault. A spokesman said he'd raised roughly $9 million in the last three months of the year but that he would spend most of it to compete in Iowa. It is also unclear how much money the pro-Gingrich PACs have raised.

Gingrich said it is not negative "to accurately describe someone's record."

"He doesn't tell the truth," Gingrich said.
