According to former Colorado Congressman Tom Tancredo, President Obama withheld his birth certificate to make the Republican Party look "like nuts".
Tancredo's theory omits one important and self-evident fact: many Republicans in Congress or running for office do not need anyone's help to look nuts. All they have to do is move their lips, and something nuts will naturally flow.
Think of Sarah Palin's saying that she was fit for foreign policy because she can see Russia from her house. That of course is like saying that I am fit to be an astronaut because I can see the moon from my apartment.
Or think of The Donald, the bankruptcy expert who would be president if he can find enough nut-job Republicans to vote for him, who basically said that America needs a man with the balls to call 1 billion plus Chinese "motherfuckers" because of their unfavorable trade policy to America (while neglecting to mention that part of his clothing line is made in... yes, China.)
But if two examples are not enough for you, go to this YouTube gallery of Republican horrors, ten minutes of hard-to-endure, inane, offensive, and bat-shit crazy statements by a variety of Republican characters, including common folk.
