It's easily possible that Zer0 has been unfit since b4 he was immaculated.
Just consider his stated views of the US Constitution.
I just visited the web sites of CNN, ABC, CBS, ABC. Only CBS had any sort of story about Libya. It was was about Witnesses saying it was an organized attack. All the other sites had very prominent stories favorable to Obama. None favorable to Romney. Several unfavorable to Romney.One had a story about how the presidency had affected Obama's faith.
The thing I have trouble understanding is how did anyone ever think he WAS fit to be president. Okay, if a person is admittedly mentally handicapped that is different but anyone with an IQ above 90 should have known better.
