PRINCETON, NJ -- The latest Gallup Poll Daily tracking update shows voter preferences holding steady, with 46% saying they would vote for Barack Obama and 43% for John McCain if the presidential election were held today.
The figures are unchanged from Sunday's report, and in general reflect the remarkable stability in the numbers for the past two-plus weeks. Over this time, Obama's support has ranged between 46% and 48%, while McCain's share of the vote has been in the 42% to 44% range. Thus, Obama has consistently held a modest, but consistent, advantage over McCain for the past two weeks, and for all but three days since early June.

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 11-13, 2008. For results based on this sample of 2,604 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.
