The Obama campaign is so very very serious and trustworthy. This image appeared on its official tumblr site today, with the tagline “Sums it up.” Mitt Romney is seen wearing a dunce hat, on which is printed a map of the world.

The implication is obvious: Mitt Romney is a dunce when it comes to world affairs.

Meanwhile, the president whose campaign hosted the photo is embroiled in a massive scandal that involves world affairs, lies, video, a cover-up, and a body count.

If there is a photo that truly “sums it up,” it might be this one.

Or maybe it’s this one.

Or perhaps this one, in which Barack Obama bows to the Saudi king.

A tip of my non-dunce hat to Drudge.
