The problem is the concept of the "caucus" itself. You can't participate if you're not there. If you fell like you are going to be talked down to, you probably won't be there.
                   If you're at work, or stuck in traffic, or picking up the kids, you can't be there. Professional people and retired people have no trouble getting to the caucus. College students can get there--even if they cut class, they'll probably be excused.
                   So the causcus provides a means of making decisions to help everybody except the people who need the help the most.
                   It's an elitest process.
