Earlier this week, Palin challenged President Obama to a foot-race, claiming she had the endurance to win a "long race". Yeah, right, when her legs are about half as long as Obama's... She is, indeed, an idiot. White House spokesman Robert Gibbs' response was that he would ask the President "if he's got any free time in his summer to do that." In other words, Sarah, Obama is much too busy dealing with the business of the nation and the threats from countries you can see from your house to bother with your self-serving little ego trip.
