They'd accuse him of using the war and it's military personel for political reasons.
He should stand back, and let others take over. He has to keep his nose clean, as to not give any fodder to the Democrats what so ever. Let others do the "dirty work" on his behalf. It's safer. That way they can't pin it on him.
He needs to stick to NJ and it's voters issues. Hold the line. No one can argue with him that way. He keeps his slate clean.
Democrats need division. That way they can attack full force. BUT, no one can hold anything against a rightous man. They have no target.
