Well, he's running for president
...probably a bit full of himself and an authoritarian, while we're at it.
The way politicians market themselves in capitalist elections: We're supposed to believe that our leaders are ubermensch. They market themselves as superior to the rest of us (who couldn't possibly make our decisions for ourselves, of course) because given the reigns of capitalism somehow they can make it work in our interests. Yet, all they ever offer us are meager concessions.
It takes 15 years to be a brain surgeon, and no qualifications to be a president or pm. Because they're the puppets of capital. Now they just sell themselves in vapid marketing, employing media and image consultants.
Obama is very reminiscent of Tony Blair.
