PRINCETON, NJ -- Barack Obama maintains a slim advantage over John McCain in the latest Gallup Poll Daily tracking report, 46% to 43%.
These results are based on June 20-22 polling, and match the average three percentage point advantage held by Obama for the past week.
Obama received a rather short-lived bump in support right after he clinched the nomination, with his lead over McCain stretching to as much as seven points. Since then, voter preferences have been quite stable, with Obama maintaining a slight edge. (To view the complete trend since March 7, 2008, click here.)
Relatively stable voter preferences at this point in the campaign would not be unexpected, as the intensity of the campaign has died down since the primary process concluded. Obama and McCain continue to make speeches and campaign almost daily to attempt to keep themselves in the news, however, the next major events in the campaign will likely be the candidates' selections of their vice presidential running mates later this summer. -- 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 June 20-22, 2008. For results based on this sample of 2,608 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.
