In Delaware, ultra-conservative Christine O'Donnell is running for the GOP nomination for senator against moderate old Mike Castle. Most Republicans -- even ones who consider Castle a terrible RINO -- can't bring themselves to support O'Donnell, because O'Donnell is gross and crazy. Like, for example, she keeps insinuating that Castle is gay. And she is also opposed to masturbation.
But she is also a Mama Grizzly! Even though she does not have children. Still a grizzly!
Palin did this either because O'Donnell's campaign manager worked with former Tea Party candidate Doug Hoffman, whom Palin previously endorsed, or because of the Tea Party Express. Either way, O'Donnell will probably not win Joe Biden's old Senate seat.
