Yes, there's been tons of talking heads at every news outlet confusing Obama and Osama. It's quite easy to do, of course. And as mentioned in another thread, it's not just the almost identical spelling, I think what really bothers his media sycophants is that his name is a continual reminder of his "otherness". They can speak glowingly about multiculturalism all they want, I think they know that Americans still can't help but take note of the peculiarity of our President having a name that is so easy to confuse with a Middle Eastern Islamic terrorist.
How many people on September 12th, 2001 would have believed we'd have a president named Barack Hussein Obama in just a few years? I'm still struck by it every time I hear it uttered or see it printed, but then I guess I'm not like the average voter.
