How many people will show up Tuesday night? It's the topic at the water cooler this week. The Mayor's guess: one million. The Trib has a list of suggestions for the organizers to keep everything orderly. And yesterday, the Washington Post had a nice piece about how the Democratic Party hopes to return in celebration to Grant Park, the place where the party fell apart 40 years ago. Tickets or no tickets... a whole lot of people can be expected to show. It's a story we'll be watching on election day. Update: Ben Calhoun has a report on Chicago Area Residents going to extremes to get their hands on a ticket for the rally.
