(The Blaze/AP) Newt Gingrich tried to quiet unrelenting campaign criticism that he acknowledged had taken a toll as Mitt Romney stepped up insider attacks Saturday in hopes of regaining front-runner status with the first presidential vote little more than two weeks away.
Gingrich, the former House speaker enjoying a late surge in the polls, pledged to correct what he said were his rivals' inaccurate claims about him. Romney, the ex-Massachusetts governor looking for a rebound, portrayed Gingrich as a well-heeled lobbyist since his service in Congress and predicted that conservative voters will reject Gingrich as they learn more about his lengthy Washington record.
"I'm going to let the lawyers decide what is and what is not lobbying, but when it walks like a duck and quacks like a duck, typically it's a duck," Romney said.
With the Iowa caucuses Jan. 3 up for grabs, most candidates are redoubling their efforts heading into the holidays, when voters generally tune out the race.
Gingrich is their prime target. Last week alone, anti-Gingrich ads from a Romney ally outspent Gingrich by an 8-to-1 margin on television.
Gingrich cited "the extraordinary negativity of the campaign" during a call from Washington with Iowa supporters. He said he was inclined to hold teleconferences every few days so people can discuss ideas and his campaign can "encourage them to raise any of these things that you get in the mail that are junk and dishonest."
"I'll be glad to personally answer, so you're hearing it from my very own lips," he said in the forum. "We don't have our advertising versus their advertising, but you get to ask me directly."
Romney campaigned in early-voting South Carolina, where tea party activists have given Gingrich a strong lead in polls. Romney told reporters that many voters now are just beginning to pay attention to the race and will turn on Gingrich after they learn about his time in Washington and his role with mortgage company Freddie Mac, a quasi-government agency.
Gingrich's consulting firm collected $1.6 million from the company. Gingrich insists he did not lobby for them and only provided advice.
"I think as tea partyers concentrate on that, for instance, they'll say, `Wow, this really isn't the guy that would represent our views,'" Romney said after a town hall meeting with South Carolina Rep. Tim Scott. "Many tea party folks, I believe, are going to find me to be the ideal candidate."
Gingrich said the attacks on his record have been brutal, but he insisted they are exaggerated.
"I just want to set the record straight," Gingrich told his Iowa backers. "We were paid annually for six years, so the numbers you see are six years of work. Most of that money went to pay overhead - for staff, for other things. It didn't go directly to me. It went to the company that provided consulting advice."
It's a distinction without a difference, his rivals have said. Minnesota Rep. Michele Bachmann continued to criticize his tenure as a consultant and Texas Rep. Ron Paul continued an ad accusing him of "serial hypocrisy" for taking Freddie Mac's checks.
Iowa's largest newspaper, The Des Moines Register, announced its endorsement of Romney on its website Saturday evening. It was as much an endorsement of Romney as it was an indictment of his competitors.
As the Iowa vote neared, Gingrich's decision to take the weekend off from campaigning raised eyebrows given his rivals' busy schedules. Gingrich called the decision "pacing."
Gingrich has prided himself on a nontraditional campaign, but his advantages in the polls could shift if the only exposure to Gingrich comes through rivals' negative ads.
Gingrich's campaign manager noted the onslaught in a fundraising pitch to donors.
"With Newt's opponents spending $9 million on attack ads in Iowa, we need to quickly ramp up our messaging," Michael Krull said Saturday.
Anti-Gingrich ads, courtesy of Romney allies, dominate in Iowa. The Restore Our Future political action committee on Friday spent an additional $1 million on airtime, and broadcast almost $790,000 in commercials against Gingrich last week alone. Gingrich, by comparison, spent roughly 100,000 on broadcast and cable ads.
That looked to continue into the final week before the Christmas holiday.
Romney, who has kept Iowa at arm's length after investing heavily here four years ago only to come up short. His advisers note they have kept in touch with supporters of his 2008 campaign that came in second place in Iowa.
