For the second time in as many days, Sarah Palin has publicly expressed disagreement with the McCain campaign's decision to pull out of Michigan (a decision the state party is lamenting in public as well). This gives McCain two options:
1) Stay the course: This makes his running mate look like more of a ninny and adds to the state party's malaise
2) Flip flop: Wastes money in a state he's going to lose anyway, and feeds into the erratic and desperate John McCain narrative
This discord also helps to show the public once again which campaign has its stuff together and which is just lurching from one minute to the next.
Excellent work, Agent Palin. Await further orders from HQ...
