Update

It has been reported that Mr. Brannigan's senior year high school prom date is in Chicago among voters and supporters by the lake. It's expected to be a "slamin'" party.

In addition, her brother - Internet Director for the Obama campaign - has confessed to wanting to throw up from the tension.

We'll check back with Chicago later in the night. Unless Mr. Brannigan falls asleep -- then we'll check back tomorrow.
