The Progressive-Liberal-Socialist-Democrat-Elite exist with the belief that those who do NOT believe as they do are stupid, un-educated, and suffer from an inability to appreciate the "nuances" of life that they themselves hold so dear to their (sometimes) bleeding hearts. They see Palin as a threat because she succeeded while demonstrating the antithesis of what they believe deserves success.
1. she did not have a power base from which to start;
2. she began in politics to get something done, instead of just grousing about it;
3. she didn't try to pander to a power-elite, but ran against it utilizing (horrors) a grass-roots movement;
4 she did not see her job as an entitlement, but as an obligation...and followed through;
5. and when Progressive-Liberal-Socialist-Elite groups threatened to cost her state millions and a proper response would have interfered with doing her job as Governor, she resigned to take care of business rather than make her state and it's citizens pay for defending her against the Progressive-Liberal-Socialist groups.
She did not achieve her goals by being a "token" or an affirmative action hire...she did it the old fashioned way...by earning it. No payoffs, no promises, except to do her job.
That kind of success is impossible according to Progressive-Liberal-Socialist-Democrat-Elite lore...just cannot happen. That it did happen needs to be hidden by them in a blizzard of lies and attacks...and that is just what they have done. And it is why they continue even after apparently accomplishing their goal...because if the corpse ever rises, the see their own Armageddon. To prevent that, there is no such thing as overkill.
