From my personal experience, this age group is the most ignorant about current events and politics. Rock stars they know - policy and practices, not so much.
In the early 90's, I was a non-traditional college student, after spending six years in the military. I took a few political science courses where out of 100 "traditional" students, I was the only one who participated in class discussions. Kids were completely clueless, and I have no idea how they passed the course (assuming they did).
The professor was a lib, and he knew I was a conservative, based on how I responded to his questions. Believe it or not, I learned a few political principles and concepts from him, and we respected each other despite our political differences. I aced two courses with that professor.
