Delaware has closed primaries, meaning only those voters registered for a certain party may vote in that party's primary. For a primary election, party affiliation can be changed anytime except from the last Saturday in May through the date of the Primary. For presidential primaries, party affiliation can be changed anytime except from the 59th day before the Presidential Primary through the date of the election.

You may vote by absentee ballot in Delaware if:

• Your business or occupation prevents you from coming to the polls, including if your occupation is the care of a family member who is at home due to illness, disability, or injury
• You are a student who is away at college or university
• You are on vacation
• The tenets or teachings of your religion prevent you from coming to the polls
• You are experiencing a temporary or permanent physical disability
• You are in the public service of the United States or the State of Delaware and are unable to come to the polls

You are not required to show ID to vote in person in Delaware, but bring one of the following if you have it to speed up the process:

• A current photo ID
• Signed social security card, polling place card, or vehicle registration, a similar document that identifies you by photo or signature

If you don’t bring any ID, you’ll need to fill out a form before you can vote.
