Shame on you for trying to put us Sanders supporters in a box! I'm not young, nor white, nor a college student. I have other Sanders supporters in my circle who are none of these things. Yes, Sanders has massive leads among those demographics but that doesn't delimit his support.
I'm not trying to put Bernie's support in a box. But at the same time, I'm just not following the huge logic leap it takes to claim that Hillary Clinton has an excitement problem that's exclusive to her when, right now, she's beating him soundly.
