Ben Smith suggests that we hear so much about Sarah Palin because she's good traffic. I have an additional theory: Sarah Palin offers us all the trashy elements we value as soap opera when it comes from the family of one of our elected officials (see Carter, Billy, or any member of the Clinton clan) with the additional benefit of not actually having to worry that she'll ever be elected to any position of importance. Just a thought!
I love Sarah Palin for the same reason I loved watching 'COPS' stoned in college.
I'm no political pundit– but your theory seems a bit overconfident to me. Heard that 60% of Americans feel she is unqualified to be President this a.m., which leaves 40% who need to theoretically be disposed of, and plenty of other positions of importance theoretically open to her.
I envy your peace of mind.
