In the final days of the campaign and immediately after the results came in, Gingrich expressed anger toward Romney and the negative "Restore Our Future" campaign, stating that in the future "We are not going to go out and run nasty ads, but I do reserve the right to tell the truth ... If the truth seems negative, that may be more a comment on his [Romney’s] record than the nature of politics." A study conducted by Kantar Media's Campaign Media Analysis Group showed that by December 30, some 45 percent of all television ads in Iowa were negative ads against Gingrich; 20 percent were negative ads against Romney; 10% were positive ads for Romney; 6% were positive ads for Gingrich; 8% were negative ads against Perry; 8% were positive ads for Perry; and 3% were positive ads for Paul. Gingrich was the only candidate of the five leading candidates to face a net financial disadvantage in terms of ad money spent (as a percent of total ad money spent in Iowa) verses percent of ads run against that candidate: Gingrich was at -35%, Santorum as +4%, Romney at +10%, Paul at +17%, and Perry at +31% (the largest net financial advantage). According to data compiled by BuzzFeed, for every $1,000 spent on advertising by their campaigns, Santorum received 49 votes; Gingrich received 11 votes; Paul received 10 votes; Romney received six votes; and Perry received two votes. For every one vote received, Perry's campaign spent $478.40 in paid media, Romney spent $154.90, Paul spent $103.30, Gingrich spent $89.74, Santorum spent $20.50, and Bachmann spent $3.95. This makes the average "price per vote" about $130, taking in account only media spending. Endorsements Romney was endorsed by three of the state's five largest newspapers: The Des Moines Register, the Quad City Times, and the Sioux City Journal. The two other large state newspapers, the Cedar Rapids Gazette and the Waterloo Cedar Fall Courier, did not endorse any candidate. Few major endorsements were made by major Iowa Republican elected officials. Iowa's governor Terry Branstad endorsed no candidate. Similarly, Senator Chuck Grassley chose not to endorse any candidate. On January 2, U.S. Representative Steve King said on Simon Conway's program on WHO Radio that he would not endorse before the caucuses. On December 9, Iowa Secretary of State Matt Schultz endorsed Santorum. Prominent Christian right figures Bob Vander Plaats of The Family Leader
