I've never called in so I don't know how they screen the calls. I know they split the lines and I'm sure they look for 30-day violators and drunks, etc. But, anything close to being scripted, I just don't buy it. I think I heard a host say that the screeners try to determine if the question is on topic and appropriate.
I honestly can't tell which way Brian leans, politically.
I called c-span this month. They screen for affiliation and try to determine if comments will be on topic. That's all. You do have dems swamping it just as they have taken to dominating polls. What does Rush call them? Seminar callers.
