The key thing about Obama’s skin is not its color, but its thickness. I have rarely seen such a thin-skinned, touchy politician. When Clinton said that Obama has the “political instincts of a Chicago thug,” that’s what he was talking about - he takes offense quickly and has a long memory.

Perhaps he’ll outgrow it. In the meantime, he can do a terrible amount of damage settling scores with people who have offended. If he doesn’t outgrow, we’re in even bigger trouble. Giving a thin-skinned and hyper-sensitive man Presidential instruments of power is a worrying development.
