Venn Diagrams Can Express Political Comedy, But Let’s Get It Right

Though Venn diagrams have been around since the days of the mathematician John Venn in 1880, they didn’t become an important part of what kids leaned in school until the 1960s.  Now, of course, we see them everywhere, even when they’re used to express political comedy, e.g., the one at left.

This diagram is misdrawn, however, as it shows that all four presidents share all three characteristics, and I doubt that’s what the author intended.  My attempt at telling the story is here, and is interpreted as: only Trump shares all three characteristics.
