Ten Things You Need to Know About Iowa Caucuses Jim Malone WASHINGTON - The 2020 U.S. presidential campaign gets under way for real on Monday, Feb. 3, when voters in the Midwestern state of Iowa gather in schools, libraries and private homes to participate in the Iowa caucuses. Iowa does not always determine the eventual party nominees, but the caucus vote does play a key role in shaping the primary races and weeding out contenders with little support. Here are 10 things people should know about the Iowa caucuses. What are the Iowa caucuses? Once every four years, Iowa seizes the national political spotlight with its caucus vote. Party activists head out to local schools and other locations to express their preference for the various Democratic and Republican candidates running for president. The process can take hours, and the results are eventually used to award convention delegates to candidates who do well. How do the caucuses work? Upon arrival at the caucus site, Democrats taking part elect a local chairperson and form groups supporting the various candidates. After an initial round of voting, candidates who do not have at least 15% support among those at the caucus site are considered no longer viable. Their supporters are free to go to another candidate, and caucus-goers who support other candidates are free to try and persuade them. After this "realignment" process is complete, a final vote tally is taken and reported to the state party. The caucus results ultimately are used to allocate delegates to the national nominating convention in July committed to those candidates who draw the most support. .
