I had an argument with my favorite BO lib the other day and he used that line too. He also kept on insisting Gov Palin isn't qualified.
He kept insisting that it was because BO didn't look like any other presidents on US paper money. I finally threw that back at him and said "Well, I don't think there are any FEMALES on paper money either." The look of his shock was priceless.
My favorite presidents are Franklin and Hamilton. And 0bama.
