How many criminal charges has Sarah Palin successfully defended against?

I know none of the charges had the slightest merit, but how many charges were leveled. She had 2 choices, stay in office with liberals hounding her to resign due to bogus charges, or quit and have liberals hound her for quitting. If some liberal could make the case for a person who has several criminal charges against them to stay in office, I would like to hear it. Please understand the criminal charges would never end while she was in office. I believe immorality and criminality are resume enhancements for liberals and morality begets slander. However, republicans don't consider this to be the case. Sarah Palin would have to defend the duty of a public servant with criminal charges to stay in office
