With respect, it's interesting that whenever this reason/excuse for quitting gets brought up, it's never mentioned that she created/helped create those ethics laws which could be abused. Sooner or later, there will need to be some serious political analysis of her accomplishments, mistakes etc. by Conservatives...including, for example, her stance on man made global warming while Governor, support for a path to citizenship and apparent previous support of earmarks in Alaska such as the Gravina Island bridge. Heretofore, it's been taboo.
Some here will welcome the analysis, and others won't. Hopefully it won't get shouted down.
She killed the Gravina Island bridge 7 months into her term and reduced state earmark requests by 80% during her tenure. End of story.
