The one I went to was held at a downtown coffee shop that had a wide screen computer projector.
The attendees ranged in age from early 20's to retired folks with 30 somethings being the most predominant. Probably a 2:1 ratio of women to men.
At least 50-70 people, maybe more.
The crowd was very cliquish. During the viewing portions of the crowd were audibly whining and having hissy fits when the president was shown on the screen. When the issue of possible Nuclear weapons development was mentioned there were laughter outbursts.
I made up my mind to leave when some CIA analyst said the Bush Admin. did not pay any attention to an admission by Saddam's Son, who was in charge of the WMD back in 1991, that "I ordered all Chemical and Biological weapons destroyed".
