Gallup Daily: Obama Maintains Advantage

Leads McCain 47% to 43% in latest update

PRINCETON, NJ -- The latest Gallup Poll Daily tracking update finds Barack Obama continuing to hold a modest advantage over John McCain, 47% to 43%.

The current figures, based on July 9-11 polling, exactly match the averages for each candidate over the past two weeks of Gallup Poll Daily tracking. During this time, Obama's support has ranged between 46% and 48% in each three-day rolling average, while McCain's has registered between 42% and 44%. (To view the complete trend since March 7, 2008, click here.)

While the candidates continue to campaign in earnest and attempt to draw distinctions between themselves and their opponent, the public may not be paying the same rapt attention it was during the primaries. Thus, voter preferences appear to be fairly well locked in for the moment, with Obama as the front-runner. -- 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 July 9-11, 2008. For results based on this sample of 2,641 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.
