President Obama is concerned these days with the “young invincibles,” the 20-somethings he needs now to buy into his program, but who probably won’t because they feel (you guessed it) invincible and think they will stay so for quite a long time.

But it takes one to know one, as the irony is Obama himself is, or once was, an ultra-invincible, unstoppable and doing what people said couldn’t be done. Could he become world famous on the strength of one speech? Yes, he could. Could he beat Hillary Clinton, a president’s wife and a feminist icon? Yes, he could. Could he then beat John McCain, iconic war hero? Yes, he could do that, too, with the help of a nicely-timed collapse of the fiscal system, just at the moment he started to flag.
