CONCORD – The Secretary of State’s Office is reminding voters that Tuesday, June 2, is the deadline for a voter to change their party affiliation before the September Primary Election, which will be held on Tuesday, September 8.

It is important to note that voters are not able to change their party affiliation on election day. Undeclared voters can choose a party on the day of the Primary and change back to undeclared status after voting.

Before it is too late to change party affiliation, voters should ensure they know their party affiliation, which will allow them to vote in the primary of their choice. Voters can check their current party status here:

For voters wishing to change their party affiliation, they can now do so by mail, pursuant to Governor Sununu’s Emergency Order 43. The Application to Change Party Affiliation is available on the NH Secretary of State’s website: under 2020 Election Information. Voters can complete this form and send it to their town or city clerk’s office. Voters can find the contact information for their city or town clerk’s office here: 

Finally, voters must bear in mind that as the state navigates voting in this time of COVID-19, it is critical to get trusted, accurate election information. The Secretary of State’s Office, the Attorney General’s Office, and local election officials are the authoritative sources for NH elections information and should be relied upon for guidance.
