I've expressed this elsewhere, but this really, really sets up the chance for a serious calendar split between the GOP and the Dems.
Let's say NV goes Feb 6th for both pushes NH to Jan 30th for both and IA to Jan 22nd, which is what current rules would dictate. Fine, but now that IA, WY, and a few random territories are the only caucuses left on the Dem side, the DNC probably sees next to no danger in a no caucuses rule across the board (which I'd put at better than 50/50 odds at this point, just to eliminate the last few). IA would default to its June 4th 2024 primary for the Dems. However, the GOP keeps the IA Caucus.
So it'd look something like:
GOP:
IA Jan 22nd
NH Jan 30th
NV Feb 6th
SC Feb 27th
Super Tuesday March 5th
Dems:
NH Jan 30th
NV Feb 6th
SC March 2nd
Super Tuesday March 5th
Going to be an interestingly long gap between NV and SC on both sides.
The long wait between Nevada and SC is better for a Bernie-type. A candidate which does poorly with the black vote but can win in NH and NV has time to establish themselves as a frontrunner, instead of having a few days before their momentum is halted.
