If Obama's a dog, he's a puppy that has never been housebroken, whose owner continually babies it and never requires basic standards of behavior. President Obama has never had to make a living; he has never had to face the consequences of his behavior, whether that behavior is hanging out with terrorists, doing cocaine, or attending a racist church for 20 years. He's never been held accountable. Finally, he's being held accountable. He doesn't like it, so he's rhetorically urinating in the middle of the living room.
Obama, like a bad puppy, acts badly because he doesn't recognize that he's not in the true position of authority. The American people stand above him. He is a public servant, a servant of our will. He seems not to believe that -- in fact, he thinks that America's the dog, he's the master, and he can simply order Americans to agree with him. He's utterly disconnected from reality.
In short, Obama has to learn to obey the American public. If not, we'll continue to treat him like a bad dog. Only worse, since he refuses to learn. And in November, he'll find out that bad dogs don't get any electoral Scooby treats.
