Going rogue?

Sarah Palin continues to fascinate and confuse me. On Monday, I watched part of her interview with Bill O'Reilly. I don't understand why she resigned as Governor of Alaska, other than to fend off some frivolous and very personal lawsuits against her (which the Alaska Attorney General is legally barred from defending). I still don't know whether in her heart she is secessionist or unionist. I don't know her current agenda, and I am troubled that she is beginning to spout the accepted dogma on foreign policy, particularly on Afghanistan -- which suggests to me that, far from "going rogue", she is really going Establishment; in which case she should be treated as very dangerous to the future well-being of this Republic.
