President Obama's re-election campaign today designated 35 state, local and community leaders as national co-chairs, or "ambassadors" for the president, who will play a high-profile role in defending his record and mobilizing voters for November.

The list includes current and former Democratic members of Congress, governors and mayors, as well as business and labor leaders, members of clergy and a few local campaign organizers, a nod to the value Obama places on his grassroots volunteers.

Former White House chiefs of staff Bill Daley and Rahm Emanuel will play key roles. Actor Kalpen Modi (aka Kal Penn) is expected to lead outreach to younger voters, while actress Eva Longoria will spearhead efforts to reach women and Hispanics.

All are "proud of the president's record and leadership," the campaign said in a statement.

Also notable are the names not on the list as Obama ambassadors.

Sen. Claire McCaskill, D-Mo., played a key role for Obama in 2008 but faces a fierce re-election battle in a red state.

Neither former President Bill Clinton nor Secretary of State Hillary Clinton are listed. (Secretary Clinton cannot participate in political activity because of her role as the nation's chief diplomat.)

And despite Modi and Longoria, there are few big Hollywood stars, such as George Clooney or Jay-Z, whom the campaign had reportedly sought to enlist.

Bruce Springsteen, who stumped for Obama in 2008, said last week he won't be hitting the campaign trail for Obama this time, but still supports his re-election.
