2012 presidential run
In late 2008, several political commentators, including Marc Ambinder in The Atlantic and Robert Novak in The Washington Post, identified Gingrich as a top presidential contender in the 2012 election, with Ambinder reporting that Gingrich was "already planting some seeds in Iowa, New Hampshire". A July 2010 poll conducted by Public Policy Polling indicated that Gingrich was the leading GOP contender for the Republican nomination with 23% of likely Republican voters saying they would vote for him.
Describing his views as a possible candidate during an appearance on On the Record with Greta Van Susteren in March 2009, Gingrich said, "I am very sad that a number of Republicans do not understand that this country is sick of earmarks. [Americans] are sick of politicians taking care of themselves. They are sick of their money being spent in a way that is absolutely indefensible ... I think you're going to see a steady increase in the number of incumbents who have opponents because the American taxpayers are increasingly fed up."
On March 3, 2011, Gingrich officially announced a website entitled "Newt Exploratory 2012" in lieu of a formal exploratory committee for exploration of a potential presidential run. On May 11, 2011, Gingrich officially announced his intention to seek the GOP nomination in 2012.
On June 9, 2011, a group of Gingrich's senior campaign aides left the campaign en masse, leading to doubts about the viability of his presidential run. On June 21, 2011, two more senior aides left.
In response, Gingrich stated that he had not quit the race for the Republican nomination, and pointed to his experience running for 5 years to win his seat in Congress, spending 16 years helping to build a Republican majority in the house and working for decades to build a Republican majority in Georgia. Some commentators noted Gingrich's resilience throughout his career, in particular with regard to his presidential campaign.
After then-front-runner Herman Cain was damaged by allegations of past sexual harassment, Gingrich gained support, and quickly became a contender in the race, especially after Cain suspended his campaign. By December 4, 2011, Gingrich was leading in the national polls. However, after an abundance of negative ads run by his opponents throughout December, Gingrich's national polling lead had fallen to a tie with Mitt Romney.
On January 3, 2012, Gingrich finished in fourth place in the Iowa Republican caucuses, far behind Rick Santorum, Romney, and Ron Paul. On January 10, Gingrich finished in fifth place in the New Hampshire Republican primary, far behind Romney, Santorum, Jon Huntsman, and Paul.
After the field narrowed with the withdrawal from the race of Huntsman and Rick Perry, Gingrich won the South Carolina Republican primary on January 21, obtaining about 40% of the vote, considerably ahead of Romney, Santorum and Paul. This surprise victory allowed Gingrich to reemerge as the frontrunner once again heading into Florida.
On January 31, 2012, Gingrich placed second in the Republican Florida primary, losing by a fifteen percentage point margin, 47% to 32%. Some factors that contributed to this outcome include two strong debate performances by Romney (which were typically Gingrich's strong suit), the wide margin by which the Gingrich campaign was outspent in television ads, and a widely criticized proposal by Gingrich to have a permanent colony on the moon by 2020 to reinvigorate the American Space Program.
It was later revealed Romney had hired a debate coach to help him perform better in the Florida debates.
Gingrich did, however, significantly outvote Santorum and Paul. On February 4, 2012, Gingrich placed a distant second in the Nevada Republican caucuses with 21%, losing to Romney who received over 50% of the total votes cast.
On February 7, 2012, Gingrich came in last place in the Minnesota Republican caucuses with about 10.7% of the vote. Santorum won the caucus, followed by Paul and Romney.
On Super Tuesday Gingrich won his home state, Georgia, which has the most delegates, in "an otherwise dismal night for him". Santorum took Tennessee and Oklahoma, where Gingrich had previously performed well in the polls, though Gingrich managed a close third behind Romney.
On April 4, the Rick Santorum campaign shifted its position and urged Gingrich to drop out of the race and support Santorum.
On April 10, Santorum announced the suspension of his campaign. Following this announcement, The Newt 2012 campaign used a new slogan referring to Gingrich as "the last conservative standing". Despite this, on April 19, Gingrich told Republicans in New York that he would work to help Romney win the general election if Romney secured the nomination.
After a disappointing second place showing in the Delaware primary on April 24, and with a campaign debt in excess of $4 million, Gingrich suspended his campaign and endorsed front-runner Mitt Romney on May 2, 2012, on whose behalf he subsequently campaigned (i.e. stump speeches and television appearances).
Gingrich later hosted a number of policy workshops at the GOP Convention in Tampa presented by the National Republican Committee called "Newt University". He and his wife Calista addressed the convention on its final day with a Ronald Reagan-themed introduction.
Because FEC regulations prevent campaigns from ceasing operations until they settle their debts, the Newt Gingrich campaign was never formally dissolved. In 2016, the campaign filed a proposal to shut down without paying back its outstanding debt to 114 businesses and consultants; the FEC rejected this proposal. By then, the campaign still owed $4.6 million in debt, with only $17,000 being raised by the campaign committee over the previous year.
