Peyton Manning may be out of the playoffs, but he's still all over the airwaves as one of television's most popular pitchmen and Tiger Woods' endorsements bring in hundreds of millions of dollars.

Just imagine, as The New York Times did today, Barack Obama, as a celebrity pitchman. The author, basketball fan, and oh yes, president-elect, is famously addicted to his Blackberry (RIMM: sentiment, chart, options) smart phone.

Obama is resisting efforts to make him give up his Blackberry, despite concerns about e-mail security and the Presidential Records Act, which puts his correspondence in the official record. On just such concerns, George W. Bush gave up his email account on becoming president 8 years ago.

"I'm still clinging to my BlackBerry," Obama said Wednesday in an interview with CNBC and The Times. "They're going to pry it out of my hands."

The Times asked advertising executives just what Obama could make as a celebrity pitchman for Blackberry in the event he gave up his new day job. Estimates ranged from $25 million to $50 million.

"This would be almost the biggest endorsement deal in the history of endorsements," Doug Shabelman, the president of Burns Entertainment, told The Times.

RIMM has not commented on Obama's enthusiasm for its product. And instead of Obama, it recently struck a sponsorship deal with guitarist/singer John Mayer. We're sure John will do fine, but let's get real. Jennifer Aniston's boyfriend vs. The Leader of the Free World??

Just for the record, RIMM swooned with the rest of the market last year, but has recently staged a comeback. Daily pictures of the President of the United States clasping his beloved Blackberry can only be good for business.

Steve Jobs take note. Obama also uses a Macbook. Just sayin'.
