Just when you think you've got the presidential race figured out, something comes along to upend your carefully wrought conclusions.
Mainstream media provided lavish coverage of Barack Obama's trip abroad the week of July 21-25 and predicted he would get a bounce in the polls. Some of his supporters believe he has put the election away. Other observers employ the hackneyed and meaningless phrase, "It's his to lose."
The poll numbers tell a different and more nuanced story. The two national tracking polls showed Obama getting a bounce while he was in Europe, especially after his speech before 200,000 or so Berliners in the Tiergarten. Gallup showed him rising from a 46 percent-42 percent lead on July 22 to a 49 percent-40 percent lead on July 26. The Rasmussen tracking poll showed him rising from a 47 percent-45 percent lead on July 23 (reflecting the previous days' polling) to 49 percent to 43 percent on July 26.
But over the next several days, Obama bounced back down. Gallup showed him leading by a statistically insignificant 45 percent to 44 percent as of July 31. That's the closest the race has been in Gallup all that month. Rasmussen had him down to 48 percent to 46 percent on the same day. The world tour bounce has begun to look like a bubble.
Obama may have gotten some lasting benefits from the trip. He can now say that he has been in Afghanistan and that he has visited Iraq for the first time since January 2006. Iraqi Prime Minister Maliki's seeming acceptance of Obama's withdrawal timetable may have undermined John McCain's argument that an Obama presidency could lead to disaster there. And there are a substantial number of American voters who will be attracted by a candidate who seems to pass what John Kerry in 2004 called a "global test."
Still, the basic dynamics of the race haven't changed. Obama appears to have a small lead. But he doesn't come close to maximizing the Democratic vote. And there is some evidence that the balance of enthusiasm has shifted and that young people -- who seemed to turn out and vote for Obama in unusually high numbers in the primaries and caucuses -- are no long so enthusiastic about him.
