Obama leads McCain, 46% to 42%
PRINCETON, NJ -- After moving into a nine percentage point lead over John McCain in Gallup Poll Daily tracking of national registered voters this past weekend, Barack Obama now leads by just four points, 46% to 42%.
Today's results are based on Gallup Poll Daily tracking from July 27-29.
The percentage of voters favoring Obama for president swelled from 45% in July 21-23 tracking, conducted at the outset of Obama's weeklong visit to Europe and the Middle East, to 49% in July 24-26 interviewing conducted at the height of publicity surrounding the tour. At the same time, McCain's support ebbed from 43% to 40%, and the percentage of undecided voters fell from 7% to 4%.
With Obama now back on U.S. soil and filling less of the nightly news, voter preferences have reverted to their pre-trip levels. (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 July 27-29, 2008. For results based on this sample of 2,682 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.
