When you're no longer able to do the job you were elected to do, the right thing to do is step aside. That's what Sarah Palin did. Instead of Palin & her staff spending their time defending frivolous lawsuits & dealing with an avalanche of paperwork due to numerous FOIA requests, she resigned so the state could move forward.
Due to the state's ethics laws at the time, Palin was responsible for her own legal fees. By the time she resigned, her legal bills exceeded several years' income. Then again, that was one of the goals of the individuals filing the lawsuits....bankrupt her family.
