The MSM sees her as the ideal Repubidiot the desire from them to have her front and center plus her insatiable desire to be front and center is a perfect match.
The sad thing is that Sarah's fan-base is the Ignorant Right. She does say some good things "drill here", "Obamacare, bad" but her personal intellect and total comprehension of the full political reality has made her a character. Plus, when she resigned as Gov. of Alaska that forever branded her a quitter.
The sooner she can move back to the background the better.
