I am guessing a senate run....The McCain political machine did a real number on her viability as a presidential candidate. but I can see it happening in 12 years. but first she has to repair the damage.
Matthew 2:19-21
19 But when Herod was dead, behold, an angel of the Lord appeareth in a dream to Joseph in Egypt,
20 Saying, Arise, and take the young child and his mother, and go into the land of Israel: for they are dead which sought the young child's life.
21 And he arose, and took the young child and his mother, and came into the land of Israel.
