Will McCain's womanizing be the Democrat's "October Surprise?"?

McCain cheated on his wife, who raised his children while he was in Vietnam, and then married Cindy McCain one month after serving his wife divorce papers while she was recovering from a crippling injury in the hospital. He's rumored to have cheated on Cindy as recently as February. Isn't it hypocritical to support McCain while being so against Bill Clinton for the same behavior?
