It 's not the Occupy Wall Street protesters yelling `` mic check '' who are bugging Newt Gingrich at his events these days . It 's the attack ads occupying the airwaves in Iowa . A new spot from the pro-Mitt Romney super political action committee Restore Our Future starts with the simple question : `` Know what makes Barack Obama happy ? '' The answer : `` Newt Gingrich 's baggage . '' In the ad , luggage bearing the names of the former speaker 's past liabilities then spills out onto an airline baggage carousel . `` Newt has more baggage than the airlines , '' the ad says . The spot does n't mention Gingrich 's personal baggage . But it might as well . Gingrich has demanded that Romney call on the super PAC to pull its negative ads . `` I object to lies . I object to negative smear campaigns , '' Gingrich said Tuesday . But Romney makes no apologies . `` If you ca n't stand the relatively modest heat in the kitchen right now , wait until Obama 's hell 's kitchen shows up , '' Romney said in New Hampshire on Wednesday . Unfortunately for the former speaker , it 's about to get hotter . The 2012 campaign is now a high stakes version of Pac-Man . In the battle of Romney versus Gingrich , guess who the ghost is ? The Restore Our Future super PAC is not only run by former Romney political operatives . It also is funded in large part by big donors who still work at Romney 's former investment firm , Bain Capital . None of this is a mystery to Gingrich . `` We need to understand that these are his people , running his ads , doing his dirty work , while he pretends to be above it , '' Gingrich said Tuesday . According to an analysis of disclosure forms from Restore Our Future conducted by the nonpartisan government watchdog Center for Responsive Politics , the pro-Romney super PAC has spent $ 430,380 on ads in Iowa . That 's more than the $ 325,770 spent by the Romney campaign . Combined , they are outspending Gingrich in Iowa by more than seven to one . Bain employees have given $ 1.25 million to Restore Our Future . Contrast that to the $ 84,500 contributed by Bain employees directly to the Romney campaign . Contributions to federal candidates are limited to $ 2,500 . There are no limits on donations to super PAC 's . That 's part of what makes them super . In its landmark 2010 decision in the case of `` Citizens United vs. the Federal Election Commission , '' the U.S. Supreme Court green-lighted the activities of super PAC 's , effectively allowing them to legally raise and spend unlimited amounts of money . Viveca Novak with the Center for Responsive Politics said Bain 's connection to `` Restore Our Future '' gives Romney a clear advantage in the race . `` He automatically has access to extraordinary amounts of money through these individuals who are connected to securities and investment firms , which are part of the world he used to inhabit , '' Novak said . Romney has suggested he has no legal authority to pull the super PAC spots . `` My goodness , if we coordinate in any way whatsoever , we go to the big house , '' Romney said in an interview on MSNBC 's `` Morning Joe . '' Novak said Romney could do more . `` If Romney wanted to he could call a press conference and call on the super PAC to take down the ad , '' Novak said . Romney defended `` Restore Our Future '' by pointing to the pro-Obama super PAC , Priorities USA , which has already started attacking his campaign . That PAC , run by former White House Deputy Press Secretary Bill Burton , has one spot featuring a now infamous photo of Romney during his days at Bain . The picture shows Romney in a suit stuffed with money . As Romney has pointed out , the president 's advisers have set their fundraising goal at $ 1 billion . The Romney campaign said its own spots are positive . Its latest ad stars Romney 's wife , Ann , who extols the virtues of good moral character . `` If you really want to know how a person will operate , look at how they 've lived their life , '' Ann Romney says in the ad . That sounds like another subtle swipe at Gingrich , who has a new ad featuring his wife , Callista . `` From our family to yours , Merry Christmas and Happy New Year , '' she says in the spot . With super PAC fever spreading , a little holiday cheer does n't hurt .
`` Super '' political action committees are spending millions of dollars on ads in Iowa . One group supporting Romney has been attacking Newt Gingrich . The ad says that he is a ``tax cheat” and accuses him of being part of the Washington establishment.
