Taranto comes up today with another gem in the genre:

Here's Forman's argument, encapsulated into a syllogism:

If someone is not a socialist, he is not a communist.
Obama is not a communist.
Therefore, Obama is not a socialist.

The technical term for the fallacy Forman has committed is "affirming the consequent": mistaking a necessary condition for a sufficient one.

In other words, (A=>B) => (B =>A). One of the most basic principles of Pepean Logick, explained in a succinct way.
