I'm just curious about how skewed a poll can be? Unless you are really for or against something I would assume most people wouldn't take the time to answer a poll.
as skewed as they want. plain and simple. Is a Harris poll any better then an AP poll?

or an xyz poll?
I remember about 15 years ago, I got a call from a political sounding organization, they asked if I would participate in their poll. I said ok. first question was what party was I affiliated with, I answered None. They said thank you very much, have a nice day, and hung up.

In College, I took a statistics course, one thing I remember, is that a lot of the surveys/ polls are done by charts. In other words, how you answer one question, determines what question they ask you next.
