You can register to vote in Idaho either prior to or on Election Day. An elector must be a U.S. citizen, be 18 years of age, be a resident for 30 days prior to the election, and not have any disqualifications. If a person has been convicted of a felony, he or she must have his or her rights restored before voting.
To register on Election Day, the person presents a picture/photo identification at his or her polling place. If that same photo contains (for example, a driver’s license) the person’s current address, he or she then completes the registration form and is allowed to vote. If the photo identification does not have the person’s current address, he or she needs to bring an additional piece of proof of current address (such as a utility bill).
Important changes regarding Idaho voting laws
Due to a new state law, Idaho will have a closed primary election system in May 2012. This means that unless a party chooses to allow others outside the party to participate in its primary election, only registered voters of a political party may vote to select their party’s nominees. If you are already a registered voter you can sign the Idaho Political Party Affliation Form to declare your party affiliation. If no political party is selected, you will be registered as unaffiliated (no political party preference).
