I bet everyone but me knew this already, but the DuPage County Election Commission is now making Sample Ballots available online.  This is a ballot that is exactly (?) as it will appear in your precinct when you go in on election day to vote.  (And that's a non-trivial thing.  Sure, we all live in DuPage County, but which Congressional District?  Which State Rep District?  Which County Board District?  What referenda are on your ballot?  Etc.)

Go to this link at the Election Commission (yes, it says "Voter Status lookup") and enter your information.  What you get is a page showing you your polling place, your representatives and then over on the right-hand side of the page, you'll see some PDF images that link to sample ballots.

Very cool!
