There is a lot of speculation over why Sarah Palin is stepping down as governor of Alaska. Some say she's trying to better position herself for a run at the presidency in 2012. Others say she's tired of all the Republican barbs blaming her for McCain's loss. Her administration is also the target of several ethics related probes in Alaska. Finally, there's even a rumor saying that there are some emails about to become public that confirm her husband is a member of an Alaska separatist group. And what could be more patriotic than pushing for secession from the United States?
And they're all wrong. The real reason she's quitting is that David Letterman was right: Alex Rodriguez did knock up her daughter at Yankee Stadium a few weeks ago.
