Candidates announce Labor Day kickoffs

Hillary Clinton announced this morning that she and her husband, who happens to be a former president, will double-team the traditional fall campaign kickoff this weekend.

The Clinton campaign said it will be the Hillary and Bill show as they spend Sunday in New Hampshire, which will hold the nation's first primary, though it's not clear yet exactly when that will be.

They will spend Labor Day in Iowa, which will hold the first caucus. That date is also uncertain because of other states trying to move up in the nominating calendar.

The New York senator is the clear front-runner among Democratic presidential contenders, leading in national, New Hampshire, and Iowa polls.

John Edwards, on the other hand, plans to focus his efforts on Iowa. His campaign today announced a three-day series of events there, culminating in the South Central Iowa Federation of Labor's Labor Day Fest on Monday in Des Moines.

"Labor has been the most important anti-poverty movement in American history and the best tool for strengthening our middle class and helping build One America," Edwards said in a statement. "I am looking forward to spending the weekend visiting with workers and caucus goers to discuss my plans to build One America where working families have a chance to get ahead, guarantee quality, affordable health care to every American and end the war in Iraq."

To the consternation of some of his backers in New Hampshire, the former North Carolina senator is putting the vast majority of his chips in Iowa.

Barack Obama plans to take Saturday and Sunday off, then campaign in New Hampshire on Monday and Tuesday.
