Presidential Primaries, Caucuses and Voting Rules

States and political parties use different methods to select presidential nominees. The two main types of nominating contests are:

• Primary: An election in which eligible voters cast ballots for their preferred presidential candidate.
• Caucus: A party-organized nomination process that may involve meetings, ballots or other delegate-selection procedures.

Primary participation rules also vary by state and party:

• Open: Eligible voters can generally choose which party’s primary to participate in, regardless of party registration.
• Closed: Participation is generally restricted to voters registered with the party.
• Open to unaffiliated: Unaffiliated voters may participate, while voters registered with another party generally cannot.
• Partially open or closed: Additional registration, affiliation or party-specific restrictions may apply.

Presidential primary rules may differ from those used for regular state elections. Expand a contest in the calendar for available participation details, and consult the appropriate state election office or political party for official voting requirements.

2028 Presidential Primary Delegates

Presidential candidates compete for delegates to their party’s national nominating convention. Delegate totals and allocation methods vary by state and political party.

Republican contests may use proportional, winner-take-all or other allocation methods. Democratic pledged delegates are generally distributed proportionally among qualifying candidates under party rules.

Verified 2028 delegate counts will appear in the calendar’s expandable contest information as they become available.
