Hagel and McCain will never be presidential material. They will NEVER make it past the primaries. If they are going to run, I suggest they run as independents because they will never stand a chance of even being on the ballot otherwise.
Unless they follow the Hillary strategy of appearing to go right...for the primaries...hoping that they don't slip into their real RINO personas.
McCain sunk his boat with his attack on Don Rumsfeld.
