When does the 2024 Iowa caucus end, and when did results for previous election years come in?

Washington — The Iowa caucuses are set to get underway Monday evening, as the GOP presidential hopefuls set their sights on the Hawkeye State and the possibility of a first-in-the-nation boost to kick off the primary season. But exactly when a victor will emerge remains unclear.

The caucuses are set to begin at 7 p.m. CT and will likely conclude within an hour, when vote counting will commence. But timing differences are expected between the more than 1,600 precincts throughout the state that vary in size.
