Here is video of Geraldo Rivera this morning on Fox and Friends where he analyzed the current military situation in Afghanistan and Pakistan. He had been talking about Hillary Clinton calling out the Pakistanis, where she said they had to know if Osama bin Laden is in their country. That's when Geraldo made a real slip, especially for someone left of center.
At around the 1:55 mark, Geraldo proceeded to say this President - "Osama bin Laden" - and then he caught himself, and was terribly embarrassed. Others on the couch told him it was "okay."
If a conservative had done this, they would be accused of doing it on purpose. Obviously, this was an innocent mistake by Geraldo. This just goes to show that it is fairly easy to confuse the names Obama and Osama - even for a liberal.
