Democratic voters in Iowa are set to start choosing the person they want to be the next president of the United States as the race to become the party’s nominee for the 2020 election hots up.
– What are the Iowa caucuses and why do they matter?

The caucuses are the first opportunity for Democrats to express their preferences in what has been a long and tumultuous primary. They set the tone for the month-long sprint through the early primary states, after which the field of candidates is typically culled. The winner usually receives a boost in media attention and fundraising that can propel them through subsequent contests. An unexpectedly bad performance, meanwhile, can hinder a candidate.
The caucuses do not always pick the eventual nominee, but for Democrats they have been more predictive – every winner since 2000 has gone on to become the Democratic nominee. And historically, they have been known to catapult underdog candidates’ campaigns to prominence – like they did with Barack Obama in 2008, or Jimmy Carter in 1976.
– Where and when do they take place – and who participates?

Some precincts could have hundreds of Iowans turn up, and some may have fewer than 10. The 2008 Democratic caucuses set a record when nearly 240,000 Iowans turned out; this year, party operatives are expecting turnout to be big, but not likely to be record-breaking.
Any registered Democrat who will be 18 by election day can participate, which includes 17-year-olds with an upcoming birthday. And Iowans can newly register or switch their party registration at their caucus site on the day – so campaigns have been courting disaffected Republicans and new voters across Iowa.
– What happens at a caucus?

When all the caucusgoers at a precinct have signed in, the attendees elect a caucus chair, who directs the proceedings. Representatives of the campaigns have an opportunity to stand up and give a last-minute pitch for their candidate, and then the caucuses begin, with a process known as the “first alignment”.
That is where attendees gather in the designated area for their favoured candidate. In most precincts, any candidate that receives the support of 15% of the people in the room is considered “viable” and moves on to the next round of voting. Caucusgoers who chose a viable candidate in their first round are locked in and cannot choose a new candidate in the second.
Supporters of candidates who did not meet that threshold, however, have four options: they can support a viable candidate, or join with supporters of another non-viable candidate close to 15% support to get them to viability. Alternatively, they can try to entice supporters of other non-viable candidates over to theirs to get them over the threshold. Or they can go home.

At the end of realignment, the caucus chair takes a final count of the room, and transmits the numbers to the Iowa Democratic Party.
– How are the results calculated?
The results in each precinct are used by the Iowa Democratic Party to calculate what is known as the “state delegate equivalent”, or how many delegates each candidate gets at the Iowa Democratic Party convention. That number ultimately translates to how many of Iowa’s 41 national delegates each candidate gets at the national convention.
– How are this year’s caucuses different from years past?

This year, there are only two rounds of alignment, rather than the multiple rounds in years past, and supporters of a viable candidate after the first alignment are locked in to that candidate. In previous caucuses, every attendee could choose a new candidate on each realignment.
The satellite caucuses are new, and the Iowa Democratic Party is allowing attendees to check in early rather than at their precinct site, a move aimed at cutting down on the long lines and wait times in years past.

The Associated Press will be deciding the winner based on state delegate equivalents – but with more data being released, the campaigns have signalled they plan to spin the numbers in their favour, whatever the eventual result.
