On Sept. 18, Grand Valley State University will host the Secretary of State’s mobile office unit to encourage students to register to vote in the upcoming presidential election. The unit will be open from 10 a.m. to 4 p.m. near AuSable Hall. Representatives from the Secretary of State’s office will be available to answer questions for students looking to vote and even register to vote. The last day for registration is Oct. 9. While visiting the unit and registering to vote, students can also renew their licenses, tabs or registration, as well as add themselves to the organ donor list. The mobile unit will visit 20 different universities as part of the 2012 ExpressSOS voter registration drive.
