That Sarah Palin is dumb is accepted wisdom on the left. Some on the right preached that same Gospel though, after the recent primary, perhaps no more. Consider.
Last July, Mrs. Palin resigned as Alaska's governor which pundits alleged marked the end of her political career. Since then, personally she has earned millions with her book, appearances and television contract thus insulating her from having to worry about the mortgage. Next, she made several endorsements of primary candidiates, most of whom won, and each of whom is in an important presidential primary and electoral state. (E.g., Terry Branstad in Iowa; Nikki Haley in South Carolina; Rand Paul in Kentucky; Rick Perry in Texas.) She demonstrated real loyalty by endorsing McCain in Arizona and double smarts by endorsing Carly Fiorina in California which will get her a filthy rich Senator supporter or a filthy rich supporter in future Palin campaigns. In all, the last 11 months have been pretty good for her. She's made millions, improved her political heft, remains a popular feminine icon and has been a consistent winner in politics and business.
Maybe Sarah Palin is dumb. Maybe not.
