Palin can benefit from a study of The Iron Lady.
There are moments when that "stately dignity" is just the right thing.
The folksy moose-hunting mom, bitch-on-wheels persona, blended with the dignified Iron Lady thing will be someone with broad appeal (no pun intended).
What she will also need is more exposure. Lots.
The Conservative base wants to like her (and already does, really), and wants to hear from her that she will not abandon them.
The "more refined" conservative (?) part of the base will need to be shown the regal side.
And, finally, she needs the velvet-over-steel countenance that Maggie did so well.
Oddly, I think she can do all that.
She needs to make her allies comfortable and her enemies squirm.
Career line? Governor. Keep Alaska above the fold. Drive prosperity.
And hunt more moose.
