PRINCETON, NJ -- Democrat Barack Obama and Republican John McCain remain statistically tied in the latest Gallup Poll Daily tracking update for July 31-Aug. 2, with Obama at 45% and McCain at 44% among registered voters.
The results reflect a fairly steady pattern of voter sentiment over the last several days, with the two candidates either tied in an absolute sense, or in today's average, statistically tied. As has been the case all summer, the race appears to be settling back into a pattern where Obama has a small margin over McCain. The overall average margin for June and July has been three percentage points in Obama's favor, despite some brief periods of time when Obama led statistically and other times when the race was tied. Obama has been unable to sustain a significant lead over McCain, and the latter has been unable to break into even a small lead over Obama.

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.
