what was I cheering for again?

I was watching some of the candidates' speeches tonight, and when watching Clinton's speech I had to momentarily wonder, where the hell is she?  A high school?   There are these kids behind her, some of which are obviously paying very little attention to her speech, but are cheering wildly about whatever it is that she's saying.  Like when she's talking about kids who can't pay for college, they cheer.  Yay for the uneducated!  In the meantime, did you see what that girl over there is wearing?
