PRINCETON, NJ -- According to Gallup Poll Daily tracking from July 29-31, John McCain and Barack Obama are now tied at 44% in the preferences of national registered voters.
This is not much different from the results reported in Gallup Poll Daily tracking on Thursday, when the two were nearly tied with 45% for Obama and 44% for McCain. However, it is a substantial turnaround from earlier this week when Obama held a statistically significant lead coming off his high-profile trip to Europe, Afghanistan, and the Middle East.
Obama and McCain were closely matched in each of the three nights of interviewing included in today's result, with neither candidate ahead by more than three percentage points. This suggests that the recent surge in voter support for Obama has truly subsided.
The contrast between Obama's recent advantage over McCain (ranging from six to nine points) and today's result is particularly notable because this is McCain's strongest showing in over a month. The last time Gallup found the race exactly tied was in late June. By contrast, in the weeks just prior to Obama's overseas trip, he had led the race by an average of four points.
