For those unaware, a caucus is totally unlike a primary.
In a primary election, you show up to a polling place, you cast your ballot for your chosen candidate, the ballots get counted, and whoever wins is whoever wins. On to the next state!
"The Republican caucuses will convene statewide at 7 p.m. local time (8 p.m. EST), and begin with the election of a caucus chair and secretary. Only registered Republicans may participate in the caucuses and only in their designated home precincts. However, Iowans may register or change their party affiliation on caucus day. Voters must turn 18 by the November general election in order to participate."
"There is no walking around the caucus room to form candidate preference groups. That voting method was a feature of Democratic caucuses from 1972 to 2020 but is no longer in use by either party in 2024."
"The binding presidential vote functions essentially like a party-run primary, only with very limited polling hours and no accommodation for absentee voting, except for a tiny handful of overseas and military voters. There are speeches on behalf of various candidates before the voting and a variety of party business after the vote. Individual caucus chairs are allowed to exercise some discretion in how to conduct the vote, but the voting is done by secret ballot and there is no set list of candidates. Voters must be given the option to vote for any candidate they choose. In the past, some caucus sites have pre-printed the names of major candidates and provided a write-in option, but typically, voters vote by writing the name of a candidate on a blank slip of paper."
The "limited polling hours" is key here, because if you decide to step out for a smoke, or to hit the bathroom, or grab a sandwich when the vote is called, you might not get counted at all.
In previous years this has led to accusations of under-counts, over-counts, and all other manner of shenanigans.
Here's the history of the past few Iowa Caucuses and how it related to the general election:
2016:
Ted Cruz - 8 Delegates, 51,666 votes
Donald Trump - 7 / 45,429
Marco Rubio - 7 / 43,228
Ben Carson - 3 / 17,394
Rand Paul - 1 / 8,481
Jeb Bush - 1 / 5,238
Carly Fiorina - 1 / 3,485
John Kasich - 1 / 3,474
Mike Huckabee - 1 / 3,345
2020:
Donald Trump - 39 Delegates, 31,421 votes
Bill Weld - 1 / 425
I dont think anybody is excited because its not a real primary with real candidates. The fascists are running their first fake election in preparation for if they ever take power.
I don't think anyone is excited because it's a race to see who gets to lose to Trump by 30-40 points. :)
But as a political junkie, I'll follow it anyway... The big ramification is, if Desantis comes in a distant 3rd, the calls for him to drop out will be impossible to ignore.
A 3rd or worse finish in New Hampshire and he's done.
