The Iowa caucuses are not first because they’re important; they’re important because they’re first for Election 2020. Iowans have been inundated with roughly 2,500 campaign events as Democratic candidates seek to seize the narrative in the nation’s first presidential nomination contest.Iowa’s complex system of caucuses and delegates was set up, in part, to incentivize candidates to campaign statewide. The number of delegates is capped by precinct, forcing candidates to campaign beyond the state’s most populated counties. Nevertheless, candidates have paid outsized attention to Polk County, which includes Des Moines, and Linn County, which includes Cedar Rapids, because they have the most available delegates.
