In Las Vegas last summer addressing the National Association of Black Journalists, Obama acknowledged that some might be reluctant to support his candidacy out of a misguided sense of saving his life. I wrote about the Democrat from Illinois going off script for a moment and imploring the audience to take a chance, even if it meant taking a chance with his life. This after all, was what he was willing to do.

On the political hustings, Obama tries to brush off fears by reminding supporters that he is protected by the Secret Service. But former president Ronald Reagan was shot and wounded while surrounded by Secret Service guards. Two assassination attempts on former president Gerald Ford were thwarted by the Secret Service, but the would-be assassins and their weapons got pretty close to their target.

Chances of anyone being assassinated are slim. We live in a peaceful democracy. But perception is rarely rooted in reality, but rather in fear. I'll hop on the couch for a moment and speculate that some of us fear destroying a good thing by wanting it too much. A version of the adage, if something is too good to be true it probably is. But that's just me. What do you think?
