I for one hope she heads a reform movement inside or outside of the GOP. We have had need of a reformation for a good long time. Lets have term limits and transparent government—not empty words. Go Sarah Go! If she calls for volunteers to lead a new movement—I am ready.
Boo! That was and still is a very bad idea. The best term limit is the vote of the people. You can not find really good leaders very often - and when you do, the people should decide whether or not they should remain in office, not an arbitrary and proven bad-idea like term limits.
I've seen the best leaders replaced with mediocre fools all too often - because of term limits. They are a dime-a-dozen, but great leaders are few and far far between.
