These comments are posted all over the Palin threads, what they really mean is, Sarah is as dumb as a Rock, so why not just say it. </ Sarcasm>
My guess:
She will...
—Hit the stumps in 2010 campaigning for others
—Hit the speaking circuit
—Fine tune her policy message(s) during that time
—Build a large war chest during that time
—Run in 2012
