Right now if I could pick one candidate... it would be Fred.
Because Fred is trailing so far behind, it tells me people have completely lost sight of conservative values. When we see Republican's supporting people like McCain, Romney, Rudy and Huckabee as their preferred candidate... well, we're screwed.
My first choice would be to dig up Reagan and anoint him King of the United States... but I doubt that would fly so my second choice given the choices would easily be Fred.
