2016 Iowa Republican presidential caucuses

The 2016 Iowa Republican presidential caucuses took place on February 1 in the U.S. state of Iowa, traditionally marking the Republican Party's first nominating contest in their series of presidential primaries ahead of the 2016 presidential election. The Democratic Party held its own Iowa caucuses on the same day. Ted Cruz was able to defeat Donald Trump in the Iowa Caucus by winning over Evangelical caucus-goers; Cruz won 51,666 caucus votes or 27.6%, giving him a net gain of one delegate over Trump. Cruz visited all 99 counties of Iowa and held small events. Cruz outperformed his polling average, which predicted a narrow Trump victory in the caucus. Following poor performances in the caucuses, Rand Paul, Mike Huckabee and Rick Santorum suspended their campaigns.
