Now that the 2010 elections are behind us and we have the benefit of hindsight, would you preferred that she HAD NOT resigned?
Her activity since quitting has been in two areas, self enrichment and political promotion. She has succeeded wildly in the first (good for her) and moderately in the second (couldn't get Miller elected in her own state). While that's pretty good it does nothing to make her better qualified than she was on the day she quit.
