content: The intern makes note of whatever you call about. Each caller represents a fraction of all of the people who dont bother to call. Calling multiplies the perceived public opinion on any given topic. I have talked in person to senators about various topics interesting to me, and they are certainly not versed in pretty much anything. They want to know voters' positions and MAYBE a fee talking points. Even if you could speak directly to them you wpuldnt get much put of it.
