Between this and Jeff Greenfield's funny-ha-ha-attack, maybe Obama has a case for character defamation or some such thing?
My wife just caught this and paused it on the TiVo. Un-friggin-believable, if you ask me. It's sad, but there really used to be a time when I'd have chalked that up to simple human error. But the fact of the matter is, Obama scares the hell out of the machine, simply because of the passion which people feel for him.
UPDATE: Situation Room contact page
UPDATE 2: For those wondering over the context in which this appeared, it was the teaser lead-in to a piece on whether, now that Saddam's been beheaded hanged on camera and buried, the US can get back to looking for Osama bin Laden. Transcript is here.
And, whether or not this was intentional is only half the point. The matter should be addressed, on air, a retraction and apology issued.
ANOTHER UPDATE: As inclusiveheart explains below, the protocol to get graphics on the air sort of precludes the possibility that this was just one tired/hungover/incompetent typist.
FINAL UPDATE: Word has it that Blitzer apologized on air this morning and said something to the effect of "I'll be calling Sen. Obama personally to apologize." Good work y'all.
Did anyone happen to grab that apology? Posing it via YouTube would make a great bookend to this diary.
FINAL, FINAL UPDATE: Raw Story has a piece up on the "error" and the text of Blitzer's on-air apology this morning. Thanks Mike.
Instead of the "s" in Osama, CNN put a "b" making it Obama.
Illinois Senator Barack Obama

U.S. Senator Barack Obama's family name may sound similar to that of the given name of Osama bin Laden. 

According to prominent American left-wing online blog Daily Kos, which was the first to report it, CNN mixed the two up on Monday, leading into a segment on bin Laden with the title, "Where's Obama?" on ''The Situation Room'', a show hosted by pundit Wolf Blitzer. The blog posted a photo of the mistake. The author of the blog called it "character defamation." 

CNN has called the mistake "a bad typographical error". Soledad O'Brien and Blitzer apologised separately during CNN's ''American Morning'' on Tuesday.

"We want to apologize for that bad typo," Mr Blitzer said. "We also want to apologize personally to Senator Barack Obama. I'm going to be making a call to him later this morning to offer my personal apology."

Mr Obama's press secretary said the apology was accepted. He also added that he appreciated the online blogs who brought the error to light.

"Though I'd note that the 's' and 'b' keys aren't all that close to each other, I assume it was just an unfortunate mistake, and don't think there was any truly malicious intent," said Tommy Vietor, Obama's press secretary.
