Elections.
There is always a lot at stake in any election. It’s critical that you exercise your right to vote! That means not only knowing the candidates and understanding the issues, but also knowing when, where, and how to cast your ballot.
Step 1. Register to vote.
You must be registered 15 days before Election Day in order to vote.
You can register to vote at the Yankton County Auditor’s office, located in the Yankton County Government Center, 321 West 3rd, Yankton.
Even if you think you are registered, it’s always a good idea to double check on the S.D. Secretary of State’s website.
