I thought that was the point of Sarah Palin buying a house in AZ, so she could start in Senate taking McCains slot?
I thought she just wanted a place where the family could go to get away periodically during the long AK winters.
I’m not sure it was her motivation, but I read somewhere that she bought a house in AZ, and the person felt she would run for the Senate... At some point McCain should retire...hopefully. AZ deserves better.
