IOWA-- Caucus participants in Iowa have less than a month to decide which candidate they want to support in the November general election.
Since 1983, Iowa has been the first in the nation caucus, creating a huge battleground for all candidates.
"We want high participation," said Anthony Carroll, AARP Iowa Advocacy Director. "It`s a great thing we have in Iowa with our first-in-the-nation caucus. We want to show high turnout."
As of Jan. 14, 2020 there are 12 Democrats vying to become the party's nominee heading into November with Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren, former Vice President Joe Biden and former South Bend, Indiana Mayor Peter Buttigieg leading the pack.
How to vote differs for each party.
For Democrats, participants separate into groups, based on their support of a candidate. Later, a verbal vote is taken to approve the number of delegates.
For Republicans, participants simply cast a vote of support.
In order to participate you have to be at least 18 years old and a registered voter. You can register to vote the day of the caucus if you haven't already.
The Iowa caucuses will be on Monday, Feb. 3 at 7 p.m.
