State Primary Election Dates

The dates for state primaries are listed below, sorted by state and by date. These primaries are used by political parties to determine which candidates for legislative seats will go on the general election ballot on Nov. 8, 2016. (For presidential primary dates, scroll down.)

The earliest state primaries are held on March 1, and the latest in mid-Sept. June is the busiest primary month, while there are no primaries being held in July.

Eight states have reserved dates for a primary runoff in the event that no candidate gets the requisite percentage of votes. For details on how runoffs work in these states, visit NCSL's Primary Runoffs webpage.

The manner in which party primary elections are conducted varies widely from state to state. Please visit the State Primary Elections page for information on types of primaries, such as "closed," "open" and "Top Two."

Note that primary dates are subject to change.
