Former President Bill Clinton says in a forthcoming Obama campaign documentary that he hopes he'd have made the same decision as President Obama to authorize the daring raid that killed Osama bin Laden.

"He took the harder and more honorable path," Clinton says in a newly released excerpt of "The Road We've Traveled."  "When I saw what had happened, I thought to myself, 'I hope that's the call  I would have made.'"

The documentary, which is directed by Academy Award winner Davis Guggenheim and narrated by actor Tom Hanks, was produced by Obama's re-election campaign in an attempt to shape the national debate about the president's first term. It is set to premier at Obama campaign field offices around the country on Thursday.

Vice President Joe Biden also lends his voice to the effort, portraying Obama in the latest excerpt as a tough decision-maker. "It dawned on me, he's all alone," Biden says of the day the president faced the final call on the bin Laden raid. "This is his decision."

Clinton, who is stepping up his role in the campaign to re-elect the president, will reportedly appear with Obama at several re-election fundraisers in the next few months.

Biden officially begins a campaign role later this week with the first of a series of battleground state speeches aimed at framing the key issues in the general election.
