Never interrupt your enemy when he is making a mistake. - Napoleon Bonaparte
Too many times the Republicans tried this, only to give the Clintons time to run out the clock, dribble out the bad news and 'move on'. The media supported them. In this case, Donald is trumping both the Dems & the media with his ridicule.
If you are a master at heckling, as Donald is, then you add more things for the Dems to respond to and divide their attention. There is no defense to ridicule, according to Alinsky. I think that this needs to be updated - there is no defense to ridicule done right. Donald is doing it right.
The idea that time is on our side is unrealistically optimistic, when the media can go into full defense & distract mode to fix any trouble. Either we fight, or we lose.
When your enemy is stumbling, PUSH!
