If you're a potically savy, elitist from the Northeastern U.S. then it is tongue in cheek humor that even a Democrat would "get." It is also understood as the current state of affairs of where anti-Obamaism is, and where it possible go prior to election, as far as negative campaigning....
If your not in that group and you tend to be fearful by nature, and uneducated, then you might deem it to be a realistic picture of Mr and Mrs Obama.
The former will actually read the article, the latter probably would not....that is what is freigtening.
