"Sen. Barack Obama has a sizable lead over Sen. John McCain, polls show, but those numbers could be deceiving if the "Bradley effect" comes into play.
The Bradley effect is named after former Los Angeles Mayor Tom Bradley, an African-American who ran for California governor in 1982.
Exit polls showed Bradley leading by a wide margin, and the Democrat thought it would be an early election night.
But Bradley and the polls were wrong. He lost to Republican George Deukmejian.
The theory was that polling was wrong because some voters, who did not want to appear bigoted, said they voted for Bradley even though they did not.
"People will usually tell you how they voted after the election, but we found in the Bradley campaign ... that people were actually not telling us who they voted for," said Charles Henry, who researched Bradley's election.
The Bradley effect is also called the "Wilder effect," after Douglas Wilder, Virginia's former governor. He won by just one-tenth of a percent, but as he pointed out to CNN, "people forget -- in the exit polls, I was still double-digits ahead."
According to CNN's latest poll of polls, Obama is leading McCain by 8 percentage points, 50 to 42.
Some analysts say the race could be much closer or even tied if the Bradley effect is factored in."
