No one is required to sit back and let people attack you without the RIGHT to attack back. McPain started all the attacks and supporters of Obama have pretty much demanded he (or someone) respond. Self-defense is a RIGHT.
McCain's lies go back decades when he first, according to Cindy McCain "followed" her around the room. When they finally got face-to-face McCain told the lie that he was 4 years younger and she told the lie that she was 4 years older. He was also MARRIED at the time. The cheating on his first wife (who was crippled in an auto accident) did not begin with Cindy but she was a rich beauty queen so he realized he had hit the "jackpot".
