She enjoyed the notoriety too much.
Possibly but paying for the “antics” of her immediate family plus the divorce probably cost her a pretty penny.
Her time has come and gone. My Alaskan friends don’t think she can beat the “Alaskan “Mad Kow” in a head-to-head contest. (They’re not anti-Palin, supporters who are realistic about the current Alaskan political scene.) That’s what it would take for her star to rise again. Not likely !
