PRINCETON, NJ -- Barack Obama edges out John McCain in the candidate preferences of national registered voters by three percentage points, 46% to 43%.
Today's result, based on Aug. 5-7 interviewing, is identical to where the race stood in Thursday's report, and marks the fifth straight day that McCain and Obama have been separated by between two and four points in the Gallup Poll Daily tracking poll. (To view the complete trend since March 7, 2008, click here.)
It thus appears that Obama has recaptured a slight lead over McCain after essentially falling into a tie with his likely Republican opponent for a short period last week. -- Lydia Saad
Survey Methods
For the Gallup Poll Daily tracking survey, Gallup is interviewing no fewer than 1,000 U.S. adults nationwide each day during 2008.
The general-election results are based on combined data from Aug. 5-7, 2008. For results based on this sample of 2,718 registered voters, the maximum margin of sampling error is ±2 percentage points.
Interviews are conducted with respondents on land-line telephones (for respondents with a land-line telephone) and cellular phones (for respondents who are cell-phone only).
In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
