Poll Tracker

Today's daily Gallup presidential tracking poll is almost identical to yesterday's tracking poll . Both show Barack Obama with a wider lead than before his trip to the the Middle East and Europe last week.

Nationally, Obama leads John McCain, 48-40 percent. The survey was conducted July 25-27 and has a margin of error of +/- 2 points.

Meanwhile, today's Rasmussen daily tracking poll shows Obama with a slimmer lead over McCain: 48-45, also with a margin of error of +/- 2 points.
