PRINCETON, NJ -- The latest Gallup Poll Daily tracking report shows Barack Obama with a 52% to 41% lead over John McCain.
These results, based on Oct. 5-7 polling, are the best for Obama during the campaign, both in terms of his share of the vote and the size of his lead over McCain. (To view the complete trend since March 7, 2008, click here.)
Nearly all interviews in today's report were conducted before Tuesday night's town hall style debate in Nashville. Any movement in voter preferences as a result of this debate will be apparent in coming days.
Voter preferences seem to have stabilized for the moment, as Obama has held a double-digit lead over McCain in each of the last three individual nights of polling.
Concern about the economy seems to be playing to Obama's advantage; he overtook McCain when the financial crisis worsened in the middle of September, and his strong showing today coincides with the worst rating of the economy this year (59% of Americans describe current economic conditions as "poor"). -- Jeff Jones
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. 5-7, 2008. For results based on this sample of 2,747 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.
