I would LOVE to see King run for Governor but I am not sure he wants to. He loves being in D.C. I called his office and asked him to mount a primary challenge to Grassley but they wouldn't go along with it.
Just a hunch but, maybe Mr. King didn't want to (1) end what appeared to be a promising career in politics and (2) be forever remembered as a total nutjob, which is exactly what he would have accomplished by running against Grassley.
