With all due respect, you're misreading the 'toon. It shows politics being evil and harming Dubya. He is making a strong point: I would not be surprised if Ramirez is a Freeper.
I dont know the background of the person who drew this picture. I do know however that background of the incident this is depicting in history. It is difficult to figure out what he was attempting to express with the drawing.
It could well be he is showing how politics are being used to undermind his administration.
It could also be illustrating something much more sinister, (please note sinister is another way to say the word, left.)
