Or, maybe you want to run the idiot ~ where's the backup if the idiot does something idiotic ~ did you know there are, at present, four people running around loose who have attempted to assassinate Presidents? One succeeded in shooting a candidate (Wallace) as well. One succeeded in shooting a President (Reagan)
Ask yourself "who let these guys out'?
LBJ was not an “idiot” by any measure. He was a practiced and skilled politician as his Senate career easily demonstrated. The fact that he ran into a problem not susceptible to his skills didn’t make him an idiot either.
Nor is Romney an “idiot” by any stretch. Unless “idiot” is now defined as “someone you don’t like.”
Nor will I deny that there are loose cannons (or worse) about capable of derailing any political campaign. But the effective ones have rarely been delved into deeply after they have been painted as “lone assassins”.
