Bachmann’s appointment of Ed Rollins reveals her lack of judgement. The appointment of team members is the first test of the good judgement of any leader. BM has flunked her first test.
I speculate that it is a symptom of a deficit of independent judgment. On a scale that represents "inside the GOP," Bachmann is more (inside) compared with Palin, and Bachmann's tapping of Rollins was, I think, an insider's move taken on the basis of advice from insiders.
My sense is that Bachmann's political ambition is in charge of her decision-making, at the moment. She's in it for herself.
