Mitt Romney doesn't know how Venn diagrams work

From Sociological Images's Lisa Wade:

Mitt Romney’s campaign put out a set of graphics illustrating a “gap” between what Obama promised and what he has delivered. The graphic is in the form of a Venn diagram, a visual designed to show the overlap between two conditions...
Unfortunately, Romney’s overlapping circles are not Venn diagrams, making the campaign somewhat ridiculous and giving nerdy liberals all over America a good chuckle.
