So, on top of all her other failings, she's a quitter.
Her attitude is that she is not as "popular" as she thought so she doesn't want to be governor any longer. Her decision not to run for re-election means there is nothing in the Governorship for her so out she goes with short notice - and with little concern for citizens of the State of Alaska.
Either that or someone somewhere has convinced her she can run for President - meaning it will take every second available to educate her so she can handle even the most simple of questions. Questions of the type she was not able to handle during the VP "tour".
The fact that she alludes to her "family" is a joke. She had no problem turning her back on the state AND her family when she thought she could be Vice President. This is the same schizophrenic behavior she exhibits towards the issues along with other political decisions she has made in the past...ask former Senator Stevens, who she was "for" or "against" depending upon the media...
She's most interested in extending her 15 minutes or so of fame. Not doing anything of value for this country.
Not sure about her Lt Governor's record, but I am sure animals everywhere in Alaska, and more than a few humans, are breathing sighs of relief.
