Gallup Daily: Obama 49%, McCain 40%

Third day with Obama holding a significant lead over McCain

PRINCETON, NJ -- Barack Obama now leads John McCain among national registered voters by a 49% to 40% margin in Gallup Poll Daily tracking conducted July 24-26.

This represents a continuation of Obama's front-runner position evident in the last three Gallup Poll Daily tracking updates. The margin, coincident with the extensive U.S. news coverage of Obama's foreign tour, is the largest for Obama over McCain measured since Gallup began tracking the general election horserace in March.

A key question remains as to whether this "bounce" is short-term (as happens to bounces in some instances following intense publicity surrounding a convention) or if his lead will persist -- the answer to which will become evident in the next several days. -- Frank Newport
