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
the only way any of this matters is if - in a few months - Trump is, somehow, stricken from the ballots in enough states to matter or is ruled as ineligible to run at all. or if he dies.
otherwise, he'll be the GOP candidate, and these also-rans will be as irrelevant then as they are now. if he chooses on as a running mate, it'll be based on their ability to kiss his ass, not really on the polls.
well, since it's gone to SCOTUS, don't expect much movement until they make a ruling. Honestly, i expect them to realize that the only thing they can do is say, "it's a state issue," and kick it back down to the states to decide who gets on what ballot.
the only thing they might dip their toe in on is what is or is not "insurrection", although i rather doubt it because i don't know whether that's actually an issue being challenged.
well, it’s 2 issues there, really— 1) whether a state can remove Trump (or anyone) from a ballot (or maybe just a primary ballot) and 2) whether Trump committed insurrection (an issue which may preclude the other issue). They may decide to rule on issue 1 and ignore issue 2 for the reason you mentioned, or they may (more likely) decide to say that issue 1 is a state issue (which it is) and ignore issue 2 altogether as, like you said, it’s an ongoing matter in lower courts.
