City Vows To Bill Obama Campaign For All Costs Associated With Massive Outdoor Bash

CHICAGO (CBS) -- Election Day is less than two weeks away, and Chicago could be home to the biggest political party in the country. Construction is underway for a massive stage in Grant Park where Barack Obama could declare victory on election night.

As CBS 2's Joanie Lum and Political Editor Mike Flannery report, tens of thousands are expected to gather before the stage on election night. One way or another, that huge crowd will witness history.

The event would require massive security, but the Obama campaign promises that Chicago taxpayers will not have to foot the bill for police, fire and medical services that would be required for election night.
