Is McCain Setting Up Lieberman for VP by Choosing Sarah Palin?

With so many obvious negatives one wonders if Sarah Palin will remain on the Republican ticket for the White House.

Did McCain pick her knowing he would get evangelical support with the realization that he would be able to dump her because of her many negatives? Then he could seek support from another sector of the Party by choosing a new VP from that other Republican constituency.

Lieberman is the one I dread. Who set up Sarah? I ask you now. Well, she hasn't been dumped yet.
