The Iowa caucuses operate very differently from the more common primary election used by most other states (see U.S. presidential primary). The caucuses are generally defined as "gatherings of neighbors." Rather than going to polls and casting ballots, Iowans gather at a set location in each of Iowa's 1,774 precincts. Typically, these meetings occur in schools, churches, public libraries and even individuals' houses. The caucuses are held every two years, but the ones that receive national attention are the presidential preference caucuses held every four years. In addition to the voting and the presidential preference choices, caucus-goers begin the process of writing their parties’ platforms by introducing resolutions.[4]
Unlike the first-in-the-nation primary in New Hampshire, the Iowa caucus does not result directly in national delegates for each candidate. Instead, caucus-goers elect delegates to county conventions, who in turn elect delegates to district and state conventions where Iowa's national convention delegates are selected. Ironically, the state conventions do not take place until the end of the primary and caucus season: Iowa is in fact one of the very last states to choose its delegates.[5][6]
The Republicans and Democrats each hold their own set of caucuses subject to their own particular rules that change from time to time. Participants in each party's caucuses must be registered with that party. Participants can change their registration at the caucus location. Additionally, 17-year-olds can participate, as long as they will be 18 years old by the date of the general election. Observers are allowed to attend, as long as they do not become actively involved in the debate and voting process. For example, members of the media and campaign staff and volunteers attend many of the precinct caucuses. Youth who will not be eligible to vote by the date of the general election may also attend as observers and may volunteer to attend the county convention as youth delegates.
By way of historical reference: The 2008 Republican Iowa Caucuses had the following result - 2008 – Mike Huckabee (34%), Mitt Romney (25%), Fred Thompson (13%), John McCain (13%), Ron Paul (10%), Rudy Giuliani (4%), and Duncan Hunter (1%). Ultimately, the Republican Presidential candidate was John McCain.For the Republicans, the Iowa caucuses follow (and should not be confused with) the Ames Straw Poll in August of the preceding year. Out of the five Ames Straw Poll iterations, the winner of the Ames Straw Poll failed to win the Iowa caucuses twice, in 1987 and 2007.
In the Republican caucuses, each voter officially casts his or her vote by secret ballot. Voters are presented blank sheets of paper with no candidate names on them.[8] After listening to some campaigning for each candidate by caucus participants, they write their choices down and the Republican Party of Iowa tabulates the results at each precinct and transmits them to the media.[9] In 2008, some precincts used a show of hands [10] or preprinted ballots.[11] The non-binding results are tabulated and reported to the state party, which releases the results to the media. Delegates from the precinct caucuses go on to the county conventions, which choose delegates to the district conventions, which in turn selects delegates to the Iowa State Convention. Thus, it is the Republican Iowa State Convention, not the precinct caucuses, which selects the ultimate delegates from Iowa to the Republican National Convention. All delegates are officially unbound from the results of the precinct caucus, although media organizations either estimate delegate numbers by estimating county convention results or simply divide them proportionally.
So, who will win the Iowa Caucuses this year?
EDIT:
Democratic caucus participants (though not Republicans, whose caucuses vote by secret ballot) must publicly state their opinion and vote, leading to natural problems such as peer pressure from neighbors and embarrassment over who his or her preferred candidate might be. Another criticism involves the sheer amount of participants' time these events consume
Arguments in favor of caucuses include the belief that they favor more motivated participants than simple ballots, and that supporters of non-viable candidates are able to realign with a more popular candidate and still make their vote count.[citation needed] Additionally, many caucus-goers consider them more interesting due to how much more interactive they are than a primary. Lastly, one other argument in favor is that caucus-goers get more information before making their vote, so those voting will potentially be more educated about their candidate choices than primary-goers.
An Iowa caucus can last up around two hours, preventing people who must work, who are sick, or must take care of their children from casting their vote. Absentee voting is also barred, so active-duty Iowan soldiers lose the opportunity to participate, as do locally-registered college students who leave the state during winter holidays. The final criticism is the complexity of the rules in terms of how one's vote counts, as it is not a simple popular vote
