If you're not registered to vote, you have till tomorrow (Jan. 8) to do it, and it's going to be a hassle. (I'd say check here to see if you're registered, but the form appears to be broken.) Details on last-minute registration after the jump...
• Download a PDF voter registration application from the Chicago Board of Elections website, or at any public library.
• Register at any Illinois Secretary of State driver’s license facility.
• Register in-person at City Hall or the Chicago Election Board offices, 69 W. Washington, Suite 600, from 9am to 5pm, or until midnight on the 8th.
