Chicago went all Cairo today on Wisconsin Governor Scott ("I've got a baseball bat in my office") Walker as thousands of residents of the Windy City showed up at the State of Illinois Building (The Thompson Center) to protest Walker's cheesy, sleazy attempt to take away collective bargaining rights from state workers (translation: to break unions).
I'm not really very good at such things and I claim no true expertise, but I have had a little experience looking at crowds and figuring out how big they are, and I can tell you this: this was a BIG crowd. Don't believe the local mainstream sources. They're saying "hundreds of people..." This crowd was in the thousands, perhaps as many as six thousand.
The video gives only a flavor of the rally; I was too far from the podium to either see or hear the speakers very well (although I was glad to see my Senator, Dick Durbin, showing solidarity with the crowd) so don't look for speeches. But I spoke to several people to ask them why they were there. None of them were paid by wealthy ideologues to attend. They wanted to be there. Take a look and a listen.
