U.S. 2024 Iowa Republican caucus latest polls December 2023
End-of-year polling shows Donald Trump leading the Iowa Republican presidential caucus by a more than 30 percentage points ahead of Ron DeSantis. The state will hold its 2024 Republican presidential caucus on January 15, 2024
In addition to primaries, some states choose an alternative route by holding caucuses. Unlike primaries, caucuses are closed meetings organized by political parties at the local level, often within counties or precincts. The caucus process includes discussions, the formation of candidate-supporting groups, and formal voting, with delegates assigned based on the results. These delegates then proceed through county, district, and state conventions to refine the selection of candidates, ultimately leading to the national party convention. Iowa's caucus is particularly noteworthy as the first contest in the nation, setting the tone for subsequent primaries and caucuses. The outcomes significantly influence the narrative and momentum of candidates' campaigns as they vie for their party's presidential nomination.
