What do you think? It's correct?
That's where things stand now, with current state laws, but it's not going to last. The RNC has toughened its penalties this time, so it no longer makes sense for big states to defy the party rules. States like Florida and Michigan, for example, no longer have an incentive to hold their primaries so early, because the super penalty means that they'll have barely any delegates. However, there's still a chance that a small state which doesn't have many delegates in the first place will throw a wrench in things. We'll see.
Well both parties have agreed to rules for it to be:
Feb. 1 -- Iowa caucuses
Feb. 9 -- New Hampshire primary
Feb. 20 -- Nevada caucuses
Feb. 27 -- South Carolina primary
March 1 -- Super Tuesday
That's the Democratic calendar, but I don't think the RNC is that specific. I think the RNC just says March 1 or later for all states except IA/NH/NV/SC, while the chosen four states can schedule themselves for any time in February.
However, I don't think this is going to work, since South Carolina always wants a longer buffer between its primary and those of other southern states. So, "best case scenario", so to speak, would be something like:
Jan. 25 -- Iowa caucuses
Feb. 2 -- New Hampshire primary
Feb. 13 -- Nevada caucuses
Feb. 20 -- South Carolina primary
March 1 -- Super Tuesday
