Poll: Obama has 10-point lead over McCain

PRINCETON, N.J., Oct. 27 (UPI) -- Democratic presidential nominee Barack Obama has a 10-point lead over Republican John McCain nationally, a poll indicates.

The Gallup Poll Daily tracking from Friday through Sunday indicates Obama leads McCain 53 percent to 43 percent among likely voters.

"History offers few examples of a trailing candidate mounting a successful comeback in the last week of the campaign," Gallup said in its analysis, noting that presidential election trends since 1952 point to 1980 as the only case in which a candidate -- Ronald Reagan -- was behind in the Gallup Poll a week before the election, but went on to win the presidency.

The poll is based on interviews with 2,343 likely voters. The poll's maximum margin of sampling error is plus or minus 2 percentage points.
