You didn’t even begin to answer my question!
(Most ‘I love Sarah but’ Freepers don’t want to answer. Often, but by no means always, because they are the paid Mitt/Establishment guys posting here for their team’s agenda.)
As chair of the RNC, I think Sarah would have more influence on the direction of the party and it's influence on those already in congress. She would be an especially strong factor in the 2012 national elections.
Of course it's only my gut feeling; but, I don't yet see Sarah giving middle America the confidence in her ability to compete with despots on the world stage.
