The Iowa caucuses are quadrennial electoral events for the Democratic and Republican parties in the U.S. state of Iowa. Unlike primary elections, where registered voters cast ballots at polling places on election day, Iowa caucuses are meetings where voters gather to discuss and select candidates for their registered party. Political parties hold the caucuses, in contrast to most state-run primaries. Both presidential and midterm elections in Iowa use caucuses. The caucuses are also held to select delegates to county conventions and party committees, among other party activities.
Voters of the Republican Party elected state delegations to the 2012 Republican National Convention in presidential primaries. The national convention then selected its nominee to run for President of the United States in the 2012 presidential election. There were 2,286 delegates chosen, and a candidate needed to accumulate 1,144 delegate votes at the convention to win the nomination. The caucuses allocated delegates to the respective state delegations to the national convention, but the actual election of the delegates were, many times, at a later date. Delegates were elected in different ways that vary from state to state. They could be elected at local conventions, selected from slates submitted by the candidates, selected at committee meetings, or elected directly at the caucuses and primaries.

The 2016 presidential campaign of Ted Cruz, the junior United States senator from Texas, was announced on March 23, 2015. He was a candidate for the Republican Party's 2016 presidential nomination and won the second-most state contests and delegates. Cruz themed his campaign around being an outsider and a strict conservative. In the crowded early field, he chose not to directly confront the leading candidate, Donald Trump, who was also viewed as an outsider candidate. His cordial and sympathetic tone towards Trump contrasted with the more critical approach of rivals such as Jeb Bush, John Kasich, Marco Rubio, and Rand Paul. Had Cruz been elected, he would have been the first Cuban American U.S. president.
