Gallup: Obama 51, McCain 42

PRINCETON, N.J., Oct. 25 (UPI) -- Registered U.S. voters prefer Democrat Barack Obama over Republican John McCain by 51 percent to 42 percent, a Gallup poll released Saturday indicated.

The pollster said its Gallup Poll Daily tracking indicated Obama led McCain 51 percent to 44 percent using the traditional model for identifying likely voters, and by 51 percent to 43 percent using an expanded model for measuring likely voters that takes into account the possibility of greater turnout this year by people who are newly registered or infrequent voters.

The poll, conducted Oct. 22-24, suggests Obama's margin over McCain reflects what Gallup called a fairly stable lead in the presidential race 10 days prior to Election Day.

Gallup surveyed 2,793 registered voters by land line and cell phone. The maximum margin of sampling error is 2 percentage points.
