Answer:
Iowa
Step-by-step explanation:
Iowa will be the first state to have a caucus in 2020. This caucus will be held on February 3, 2020. A caucus is an event which involves people attending a meeting before they are able to vote for their preferred candidate. These meetings happen at specific locations. If a candidate gets under 15% of the vote in any caucus, their supporters will get to pick a second choice from among the candidates that remain.
