The Bradley Effect by Kate Zernike (NYT)

Article.

Basically:

In recent days, nervous Obama supporters have traded worry about a survey — widely disputed by pollsters yet voraciously consumed by the politically obsessed — that concluded racial bias would cost Mr. Obama six percentage points in the final outcome. He is, of course, about six points ahead in current polls. See? He’s going to lose.

If he does, it wouldn’t be the first time that polls have overstated support for an African-American candidate. Since 1982, people have talked about the Bradley effect, where even last-minute polls predict a wide margin of victory, yet the black candidate goes on to lose, or win in a squeaker. (In the case that lent the phenomenon its name, Tom Bradley, the mayor of Los Angeles, lost his race for governor, the assumption being that voters lied to pollsters about their support for an African-American.)

I've actually read another article which quotes a pollster from the campaign in 1982, who was saying their internal polls showed the race was a dead heat. Hopefully, this means there isn't a bradley effect, but it's america, so one can never be sure where things will land.
