You can delete your own account.
First, login to your account. To do that, go to the website at https://www.usvotefoundation.org and click on "Voter Account (login)" in the upper right corner of the screen.
Or go directly here: https://www.usvotefoundation.org/vote/MyVoterAccount.htm
After you login, you will see in the upper right corner of the screen now shows "Voter Account" and a small downward arrow. Click on that. A menu will appear. One option on the menu is "Remove Account".
If you have further any trouble, please submit a question to our Voter Help Desk.
