John McCain made quite a mistake when he decided Sarah Palin was to be his running mate. Since she became McCain's running mate last Friday, several issues and controversies have arisen about Palin that make her politically vulnerable and a liability to McCain, his campaign and the Republican Party. It's beyond me why McCain chose Palin out of all the people he was considering. Palin served as mayor of Wasilla, Alaska, with a population of 5,469, from 1996-2002, and as governor of Alaska for less than two years. This is certainly not enough experience to govern at the national level.
