The anecdotal evidence on the ground shows a serious enthusiasm deficit for Jerry Brown. That's the way it looks to me, anyway.
Take Jerry Brown's post-debate rally in Fresno over the weekend. Most of the people who showed up for the Brown rally were union workers bused in from across the state -- but the school gym where the rally was held was still just 3/4 filled, according to Bee reporter John Ellis.
I've pointed out obvious enthusiam deficits for Jerry Brown here and here and here. I'm not a polling expert, but the number of people who actually show up for Jerry Brown events like this tells you something important.
