My SO actually thought it was awesome that President Obama ordered a burger without ketchup--being a veggie, he's not a fan of the burger part, but he hates ketchup with a passion.  I don't understand it myself; I like ketchup.  I also like mustard, and like the President, I prefer spicy mustard--brown, dijon, deli, whatever.
My roommate commented that he liked how Obama ordered the burger "presidentially."
Personally, I think a person has the right to order their cheeseburger however they want to, and we shouldn't read too much into it.  Sean Hannity is just silly, but that's really nothing new.  I wonder what he would have to say about my fridge--we usually have a few different varieties of mustard.
