Poll Tracker

While Barack Obama usually has a narrow lead in polls over John McCain, a Yahoo/Associated Press poll out this morning finds that they're much more jazzed about their choice: 38 percent of Obama supporters say they're excited compared to 9 percent of McCain's fans.

And it gets worse for McCain:

• Half of McCain's backers say the race makes them frustrated, double those of Obama's.
• 65 percent of Obama's supporters say they're hopeful about the campaign, double McCain's margin.
• 24 percent of those preferring McCain say they might change their candidate vs. 16 percent of Obama's backers.

The pollsters caution everything is not completely rosy for Obama: "The poll shows lagging fervor for [Obama] by supporters of his vanquished rival, Hillary Rodham Clinton. And there are lots of dispirited and undecided independents, who are expected to be pivotal on an Election Day now less then four months off."

The poll was conducted June 13-23 and the margin of error is +/- 2.3 percentage points.
