I don't think that's true of Akin at all. It was a stupid statement but he is not a stupid man. Is Rush stupid because he started the Sandra Fluke "slut" controversy? Everyone makes mistakes. Regardless, this is a democracy. Do you want the party elders selecting your candidates or the voters? The primary voters took a look at this guy and made a judgment based on far more than you or I know about him from one interview.
If America were a democracy your rights could be taken away at whim by a majority vote of the populace.
A democracy is the very thing the Founding Fathers didn't establish.
