I don't see this as someone with an axe to grind. You're more knowledgeable than I. Where is he wrong? It sounds to me as if he's saying "Here are mistakes Simon is making, here are loser staffers he's hired, here's what he ought to be doing -- we want him to win, so here's hoping he starts doing what he needs to do while there's still time!"
Followers can't get a leader elected who either won't lead, or shoots himself in the foot. Or won't shoot.

But according to this person, Simon's campaign did everything wrong in the primary. I completely disagree.
