I am going to go out on a limb and predict a long-shot VP for Obama:
Governor Janet Napolitano of Arizona.
Look at the big shakeups in her staff announced today
http://azgovernor.gov/dms/upload/NR_081208_StaffChanges.pdfWhy?
1. Obama is about change. New guard.
2. Helps with women and many Hillary Clinton supporters
3. She is from McCain's home state giving Obama a great improvement with NM and CO.
4. Not a "Beltway insider"
Certainly a lot of reasons why she wouldn't be the choice, but everybody gets a prediction and Janet is mine.
