Methodology: Gallup is interviewing no fewer than 1,000 U.S. adults nationwide each day during 2008. The results reported here are based on combined data from Feb. 28-March 1, 2008, including interviews with 968 Republican and Republican-leaning voters, and 1,242 Democratic and Democratic-leaning voters. For results based on these samples, the maximum margin of sampling error is ±3 percentage points. 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.
