However, its important to remember that crowd size fundamentally doesnt matter much. Comparisons between how large one candidates crowd is compared to anothers are ripe for misunderstanding. Just think back to 2012, when press reports and GOP partisans frequently mentioned the large numbers that Mitt Romney was drawing on the campaign trail. Did this end up mattering? Obama won the popular vote by about 5 million votes. The history of crowdsmanship is long, and as Louisiana politico Robert Mann noted back in 2012, full of anecdotal evidence that wound up meaning nothing.
Consider the demographics of Denver, Madison, Minneapolis, and Portland: Of those four, only the Mile High City is less than 60% white (53%), and of the 50 biggest cities in the United States, Denver and Minneapolis are among the 18 that are majority non-Hispanic white. Portland is the biggest city in Maine, over 80% white, and located in the Pine Tree States most liberal area, Cumberland County. Madison is three-fourths white and an über-liberal university city its no surprise so many people showed up to see Sanders there. In fact, many college towns are going to be among the most receptive to Sanders campaign message. Take Charlottesville, VA, for example. One of the Crystal Balls writers tried to scout out Sanders when he came to the home of the University of Virginia in May, but the venue only held about 200-300 people and was packed to fire-code capacity by the time he arrived at the front of a long line. Nonetheless, Sanders smartly engaged the many who couldnt get inside with an impromptu talk.
I've said it before, and I'll say it again. Bernie is following the trail of Thom Hartmann & Ed Schultz's core audiences. I have a feeling that BS' popularity is directly tied to the markets where those two are most listened to.
