{{US 2020 presidential elections series}}

[[Presidential primaries]] and caucuses of the [[Republican Party (United States)|Republican Party]] took place in many [[U.S. state]]s, the [[District of Columbia]], and five [[U.S. territories]] from February 3 to August 11, 2020, to elect most of the 2,550 delegates to send to the [[2020 Republican National Convention|Republican National Convention]]. Delegates to the national convention in other states were elected by the respective state party organizations. The delegates to the national convention voted on the first ballot to select [[Donald Trump]] as the Republican Party's [[presidential nominee|nominee]] for [[president of the United States]] in the [[2020 United States presidential election|2020 election]], and selected [[Mike Pence]] as the vice-presidential nominee.

President [[Donald Trump]] informally launched his [[Donald Trump 2020 presidential campaign|bid for reelection]] on February 18, 2017. He launched his reelection campaign earlier in his presidency than any of his predecessors did. He was followed by former [[governor of Massachusetts]] [[Bill Weld]], who announced his [[Bill Weld 2020 presidential campaign|campaign]] on April 15, 2019, and former [[Illinois's 8th congressional district|Illinois congressman]] [[Joe Walsh (American politician)|Joe Walsh]], who declared his candidacy on August 25, 2019. Former [[governor of South Carolina]] and [[South Carolina's 1st congressional district|U.S. representative]] [[Mark Sanford]] launched a primary challenge on September 8, 2019. In addition, businessman [[Rocky De La Fuente]] entered the race on May 16, 2019, but was not widely recognized as a major candidate.

==Cancellation of state caucuses or primaries==
The ''[[Washington Examiner]]'' reported on December 19, 2018, that the [[South Carolina Republican Party]] had not ruled out forgoing a primary contest to protect Trump from any primary challengers. Party chairman Drew McKissick stated, "Considering the fact that the entire party supports the president, we'll end up doing what's in the president's best interest."<ref>{{cite web|url=https://www.washingtonexaminer.com/news/campaigns/south-carolina-gop-could-scrap-2020-primary-to-protect-trump|title=South Carolina GOP could scrap 2020 primary to protect Trump|date=December 19, 2018|website=Washington Examiner|last1=Drucker|first1=David M.|access-date=January 27, 2019}}</ref> On January 24, 2019, another ''Washington Examiner'' report indicated that the Kansas Republican Party was "likely" to scrap its presidential caucus to "save resources".<ref name=we>{{cite web|url=https://www.washingtonexaminer.com/news/campaigns/kansas-gop-likely-to-cancel-2020-caucus-not-as-needed-when-you-have-one-candidate|title=Kansas GOP poised to cancel 2020 caucus because it believes only Trump can win|date=January 24, 2019|website=Washington Examiner|last1=Drucker|first1=David M.}}</ref>

==Ballot access==
Filing for the Republican primaries began in October 2019. "Yes" means the candidate is on the ballot for the primary contest, and "No" means a candidate is not on the ballot. A “W” indicates a candidate qualified for the ballot but withdrew from the primary, the color indicating if the candidate's name appeared on the ballot (red for not on the ballot, green for on the ballot). States that did not announce candidates who are on the ballot are not included.

Bids for the Republican National Convention were solicited in the fall of 2017, with finalists being announced early the following spring. On July 18, 2018, [[Charlotte, North Carolina]]'s [[Spectrum Center (arena)|Spectrum Center]] was chosen as the site of the convention.<ref name="RNC-Charlotte">{{cite web|url=https://www.charlotteobserver.com/news/politics-government/rnc-2020/article215204290.html|title=GOP picks Charlotte for 2020 convention.

In June 2020, disagreements with the North Carolina government over COVID-19 social distancing rules caused the major events of the convention, including Trump's acceptance speech, to be moved to [[VyStar Veterans Memorial Arena]] in [[Jacksonville, Florida]]. Due to contractual obligations, official convention business was still conducted in Charlotte.<ref>{{cite news|url=https://www.nbcnews.com/politics/2020-election/rnc-picks-jacksonville-florida-convention-site-trump-accept-gop-nomination-n1230326|title=RNC picks Jacksonville, Florida, as convention site for Trump to accept GOP nomination|work=[[NBC News]]|date=June 11, 2020}}</ref>
