In 2005 the Govenator of California held a special election. Every single one of his proposed ballot measures (A collection of right-wing causes, like kicking unions) went down. His polls rating sucked. In response, the Governator shifted his political stance. To the left. He dropped all of his right wing policy proposals and started signing laws to combat global warming and giving more money to schools. He cruised to reelection.
