Currently, the DNC’s rules say that no state can hold a presidential primary or caucus before the first Tuesday in March. Iowa has long been exempted from that practice, holding its contest up to 29 days before other states. Iowa is followed by New Hampshire, Nevada and South Carolina, which also are exempted as part of the early window of voting.

Under the draft proposal, all four states — and any others interested in jumping before the rest — would need to seek new waivers to hold an early nominating contest. Up to five states would receive waivers, though the proposal does not say whether the states would all vote on the same day or whether their votes would be staggered as they are now.

If the resolution passes, it wouldn’t prevent Iowa from applying for a waiver; nor would it directly eliminate caucuses. However, it would make the “ability to run (a) fair, transparent and inclusive primary” one of its core considerations in the waiver process. Iowa is required by state law to hold presidential caucuses.
