You didn’t have to attack to attack. Better, much better, to give something to the mark: make him feel that he has one up on you. Let him pounce on your “mistake.” That makes him look unduly aggressive. Then you sprang the trap, garnering the pity by making the enemy look like a self-righteous and hyperintellectual enemy of common sense. You attacked jujitsu-style, positioning yourself as the attacked, inspiring a strange sort of protective love among voters whose wounded resentments grow alongside your performance of being wounded.
