I was listening to NPR - "Talk of the Nation," I think.
One of the guests expressed her doubts about polling in general, and an example was used that just before the CT primaries, Lamont was predicted to beat Lieberman by 14 point, while at the end, he was ahead by only 4.
There are several reasons for such skepticism:
First, many, especially younger voters, do not own land line phones, only cell phones and cell phone numbers are not readily available as the ones on the White Pages.
Second, many have unlisted number; I believe that almost 50% of Californians have their unlisted.
Third, households like ours that screen all calls in the evening. Yes, we are on the "do not call list" which leaves charities and political calls free. Especially this time of year, sometimes I do answer and someone very polite wants to update me about how the Democrats are doing and I just say that I am sorry, do not have time to talk and hang up.
Two years ago I volunteered to conduct a semi survey on behalf of the Kerry campaign. Most of the calls were answered by an answering machine. I did not go back to do this. I just imagined myself on the other side of the line and felt it was futile.
