I agree with you. Maximum chaos is achieved by Hillary being behind just slightly enough that she's willing to take the Dem Party down. If she wins big enough to be seen as the legitimate winner, then that factor is lost. The ideal outcome would be if PA was split dead-even on delegates, so the numbers don't change
Hillary is behaving like a woman in a nasty divorce fight, with the Dem party as the husband and Obama as the "younger woman". She is emotionally committed to punish those who rejected her and make them suffer, regardless of cost
That is a great analogy! Absolutely spot-on.
