Result extends presidential tie reported on Friday
PRINCETON, NJ -- Barack Obama is now favored by 45% of national registered voters and John McCain by 44%, essentially maintaining the tie at 44% reported in Friday's Gallup Poll Daily tracking report.
Obama and McCain have been closely matched in each the past four individual days of Gallup Poll Daily tracking, including in the Aug. 13-15 polling represented in today's three-day rolling average. Thus there appears to be a degree of stability to voter preferences in recent days. (To view the complete trend since March 7, 2008, click here.) -- Lydia Saad
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. 13-15, 2008. For results based on this sample of 2,690 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.
