Results of the 2012 Republican Party presidential primaries
This article contains the results of the 2012 Republican presidential primaries and caucuses, which resulted in the nomination of Mitt Romney as the Republican nominee for President of the United States. The 2012 Republican primaries were the selection processes by which the Republican Party selected delegates to attend the 2012 Republican National Convention from August 27–30. The series of primaries, caucuses, and state conventions culminated in the national convention, where the delegates cast their votes to formally select a candidate. A simple majority (1,144) of the total delegate votes (2,286) was required to become the party's nominee.

Seven major candidates were in the race to become the nominee. Michele Bachmann was the first to drop out, ending her campaign after a poor performance in Iowa. Jon Huntsman withdrew from the race after placing third in the New Hampshire primary. Rick Perry dropped out after Iowa and New Hampshire but prior to the South Carolina primary after polling poorly. Rick Santorum suspended his campaign in April after polls showed a strong possibility that he would lose his home state of Pennsylvania to Mitt Romney, and his daughter Bella's condition worsened. Newt Gingrich withdrew after insufficient funds prevented him from moving forward with a strong campaign.  On May 14, 2012, Ron Paul announced that his campaign would switch to a delegate accumulation strategy. On May 29, according to projected counts, Mitt Romney crossed the threshold of 1,144 delegates. He was formally nominated at the Republican National Convention on August 28.

Overview of results

 The delegate totals given by the AP (Associated Press),other sites such as this one and other major news outlets are a projection and have not been officially pledged yet. This applies to a delegate from a non-binding primary or caucus election, as in Iowa, Colorado, Minnesota, Maine, and Washington. These are awarded officially at Congressional and State Conventions on a later date.
 Unprojected delegates included in Total for each State. 1,869 pledged, 417 unprojected/unpledged.
 Winner-take-all states begin with the April 3, 2012 primaries, with the exception of Florida's and Arizona's primaries.

Other primary events electing delegates

Convention roll call

The traditional roll call of the states, which shows final distribution of delegates for every candidate, took place on Tuesday August 28, the first full day of the Republican National Convention.

Other candidates
Two major candidates, who had been invited to the debates, Herman Cain and Gary Johnson, had withdrawn from the race after states began to certify candidates for ballot spots. Two serious candidates who were not invited, Buddy Roemer and Fred Karger, had a very hard time getting on primary ballots and achieved only limited success. Six candidates, L. John Davis, Randy Crow, Chris Hill, Keith Drummond, Mike Meehan, and Mark Callahan, qualified for the ballot in two primaries, while the rest, over 25 in all, were on the ballot in only one, either New Hampshire or Arizona, which both had relatively easy requirements. Some votes for minor candidates are unavailable, because in many states (territories) they can be listed as Others or Write-ins. At the conclusion of the primary season, none of these other candidates was able to be awarded any delegates.

Results
Primary and caucuses can be binding or nonbinding in allocating delegates to the respective state delegations to the National convention. But the actual election of the delegates can be at a later date. Delegates are (1) elected at conventions, (2) from slates submitted by the candidates, (3) selected by the state chairman or (4) at committee meetings or (5) elected directly at the caucuses and primaries.Until the delegates are actually elected the delegate numbers are by nature projections, but it is only in the nonbinding caucus states where they are not allocated at the primary or caucus date.

Early states
Twelve states (374 delegates) voted from January 3 to March 3. Out of 374 delegates only 172 were allocated to the candidates, 18 were unbound RNC delegates, 2 were allocated for Huntsman but were unbound, and 182 delegates  were unallocated.
