Obama on Bush

Barack Obama summarizes the Bush presidency:

Everybody here knows somebody who's stubborn and wrong all the time. Why would you elect somebody like that president?

I mean, it's one thing that somebody's wrong and they know they're wrong. Or it's one thing if they're arrogant, but they're right all the time. But when they're arrogant and wrong all the time, that's a problem.
