Is Romney actually leading in the polls or are some people delusional?

Polling *has* to be a science, otherwise it's totally meaningless. If you just go around asking people questions, you can't be certain whether your sample was really random. If you go outside a church at noon on a Sunday and ask "how important is Jesus in your life" and then declare that these people represent everyone in your town or county, then you're likely to think your town or county is much more Christian than it might be.

Do you get it?

No, not really.

I get that you can't poll some people and then say that everyone is like them, but I don't see how that makes it a science.

Because how do you decide to choose a group of people that will perfectly represent the group you are trying to really get to?

That's science. I need 2000 people to represent America (a body of 300 million), how do i pick them?
