Well, there ya go.
When he was elected president he was a world-class ignoramus on economic, foreign, social and ethical issues.
You'd think that finding himself elected, intellectually helpless and hopelessly clueless, he would frantically try to "learn on the job" instead of spouting the Marxist rhetoric that got him this far.
Instead, we get juvenile globe trotting, and an endless stream of "Professor Stepin Corey" skits on TV.
Looks like learning on the job ain't his thing.
