Name: Sarah Palin
Position: Governor of Alaska
Assumed office: December 2004
She is the first female governor of Alaska, its youngest, and is the first governor born after Alaska achieved statehood. Brought to statewide attention because of her whistleblowing on ethical violations by state Republican Party leaders, she won election in 2006 by first defeating the incumbent governor in the Republican primary, then a former Democratic Alaskan governor in the general election.
She has sky high approval ratings - In July 2007, Palin had an approval rating often in the 90s. A poll published by Hays Research on July 28, 2008 showed Palin's approval rating at 80%.
She is is strongly pro life and opposes gay marriage - so she wouldn't rile the Republican base.
She would also be a blatant grab for Hillary supporters.
