So Why Did Palin Really Fire Monegan?

If Sarah Palin expects to salvage her nomination, and not become another Eagleton, then needs to come forth with a complete and believable explanation of why she fired Walt Monegan, her public safety commissioner. If it was not in retaliation for his refusal to fire her ex brother-in-law, Mike Wooten, then why *did* she fire him? She needs to speak clearly and forthrightly to this issue, otherwise it will hopelessly poison the GOP ticket.
