Are you kidding? Because of all the bogus law suits the rabid left had against her, Alaska had to pay a fortune to fight them. She left to save them - the taxpayers.
When she bowed out early, she also left a squeaky clean INCUMBANT in her place. An incumbent Republican would be harder to beat than a newbie. That was a brilliant move on her part.
It was also the absolute last thing the power hungry ‘rats expected her to do. Imagine, somebody willingly giving up power. That move probably derailed a lot of rat plans.
