BOB HERBERT of The New York Times says:

The problem is the dog that isn’t barking.

Talk for more than a few minutes with an Obama supporter in a white middle-class or working-class area and you’ll hear about a friend or relative or co-worker who has a real problem with the candidate.

When Jack Davis’s wife, Joan, who also plans to vote for Senator Obama, was asked about Democrats that she knew who would not vote for him, she replied:

“My mother! She’s 85 years old. I’m sorry to say, but she will not vote for him.”

It is frequently the case that a statistically significant percentage of white voters will lie to pollsters — or decline to state their preference — in races in which one candidate is black and the other white.

After many years of watching black candidates run for public office, and paying especially close attention to this year’s Democratic primary race, I’ve developed my own (very arbitrary) rule of thumb regarding the polls in this election:

Take at least two to three points off of Senator Obama’s poll numbers, and assume a substantial edge for Senator McCain in the breakdown of the undecided vote.
