Gallup Daily: Obama Maintains Significant Margin

Lead is eight points, 50% to 42%

PRINCETON, NJ -- Gallup Poll Daily tracking from Oct. 1-3 finds 50% of registered voters supporting Barack Obama, and 42% John McCain, for president.

Obama has now held a statistically significant lead over McCain for the last eight days, one shy of his campaign-best streak of nine days with a lead around the time of the Democratic National Convention. (To view the complete trend since March 7, 2008, click here.)

Voter preferences appear somewhat stable at the moment, as Obama has held similar advantages over McCain in each of the last three individual nights' polling. That includes Friday polling, the first interviews conducted following Thursday's widely viewed vice presidential debate, the passage of the economic rescue bill supported by both Obama and McCain, and Friday's bleak jobs report.

The presidential candidates are set to square off in round two of the presidential debates on Tuesday, answering questions asked by uncommitted voters. -- Jeff Jones

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 Oct. 1-3, 2008. For results based on this sample of 2,703 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 landline 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.
