The Complete 2024 Presidential Primary Schedule by State

The 2024 presidential primary schedule is listed below with the date of each state’s primary and caucus for Democrats and Republicans in the 2024 presidential primary. From the Iowa caucuses to Election Day on November 5, 2024, here is a look at which states vote when, and where the largest number of delegates are awarded. This page will be constantly updated with the latest information about voting dates, voting times, and delegates awarded by each primary and caucus on the 2024 presidential election calendar.

Super Tuesday in 2024 is scheduled for Tuesday, March 5.

Due to changes in the Democratic primary calendar, some early states have not decided how they will award delegates to the Democratic National Convention. These states include Iowa and New Hampshire which have been replaced as early states but still intend to hold their own contests in violation of DNC rules. Republicans will stick with the historically traditional Iowa, New Hampshire, Nevada, and South Carolina path. Democrats have embraced South Carolina and Michigan as their starting primary states in 2024.

Primary/Caucus Type

Closed – Only voters registered in their respective party may vote in the party primary
Mixed – A semi-open or a semi-closed environment, unaffiliated voters can choose to vote in either primary or voters can switch registration on the day of voting

Delegate Allocation

Democratic primary/caucus delegates are proportionally allocated to the candidates based on their percent share of the vote.

Republican primaries/caucuses delegates are winner-take-all meaning that the winner of the contest takes all of the available delegates.

Proportional – Delegates are awarded based on the percentage of the vote received by candidates, or some formulation of dividing up the delegates
Winner Take All – All delegates are given to the winner of the contest
Winner Take Most – Some delegates are reserved for the winner, some may be divided proportionally
Unbound – Delegates are not bound to a specific candidate and can support any candidate of their choosing, varying by the state party organization


* The Iowa Democratic caucus is mail-only and will be announced on March 5 (Super Tuesday)
 President Joe Biden’s name will not appear on the New Hampshire ballot due to DNC calendar rules
*** Non-binding primary. The party is allocating delegates with convention or caucus
