Lydia Saad, Gallup: “While Romney’s four-percentage-point advantage is not statistically significant, he has consistently edged ahead of Obama each of the past several days in Gallup’s seven-day rolling averages conducted entirely after the Oct. 3 presidential debate. Prior to that debate — regarded as a decisive Romney win by political experts and Americans who watched it — Romney averaged less than a one-point lead over Obama among likely voters.”
