Everyone knows that polls are not completely accurate just look back to earlier this year to pre-Iowa. If someone were to say that Kerry was going to be the nominee before Iowa many people would have laughed. But I think the most interesting thing about this poll is that Bush received a bounce after the convention and still has one. Kerry barely received a bounce so that is what I find interesting.
Another thing, it was stated in here that because telephone interviews were used than the poll is significantly skewed. Actually that's not entirely accurate. Telephone interviews are probably the most accurate you can get when it comes to a poll. The reason for this is they are in fact very random, and one of the most random polls you can take. In-person surveys at malls or on the street are not that random. Mail surveys can prove to be the most random but they are costly and people rarely do them. Although with a phone interview, not everyone can be selected for the poll, most people without phones are below the poverty and most of the people will probably not be voting meaning these people will not significantly change the poll results.
