Many people don't understand, or do understand but lie about, the
margins of error in surveys like this. They'll claim that 43,000 surveys
out of 200,000,000 qualified respondents is not valid, because "gee,
what if those 43,000 respondents happen to be all biased one way or
another. It doesn't work that way of course. You can get a very low
margin of error with a relatively small sample. In reality the CR sample
was extremely large, and even when you break it down by city, as they
did, the sample was still large.
