The Iowa Caucus is just an absurd practice .and it’s nothing but a fund raiser for the Iowa parties .way outsized in importance. Meanwhile, NH is an oddball little population with a lot of cross over voters. Neither does a good job of picking a Republican winner ..tho it works great for Dems.
The first real primary of any kind of reasonable electorate is SC, which even tho a smallish state, has a turn out of more than Iowa’s weird caucus and NH’s tiny populations combined .but then it’s on to huge Florida after only one “normal” state.
Red Hampshire ALSO hosts a lot of out of state voters on Election Day...come on up some time and check out the busses and cars with Massachusetts, Connecticut, and Maine plates...the first Tuesday of November is not exactly part of tourist season.
