2016 US Presidential elections, Iowa caucus: The First Vote

The caucuses
The caucuses are part of a four-stage election of state delegates to send to the national convention of each party. These delegates then officially nominate their national candidate. The caucuses are held in 10 US states (out of 50) — Iowa, Alaska, Colorado, Hawaii, Kansas, Maine, Minnesota, Nevada, North Dakota and Wyoming. In the remaining 40 states, primaries, a statewide process in which voters cast secret ballots, are used.

The Iowa caucus
The Iowa caucus marks the start of the US presidential race. It’s the first time that voters get to have a say in the electioneering process of their parties. Registered voters will physically assemble in 1,681 precincts, including churches, libraries and other smaller venues, across the state Monday to vote for their candidate.
