What scares me most about Sarah Palin is not her ignorance, inexperience, or ideology, but her inability to work with or even listen to anyone she doesn't already agree with. That, coupled with what has been described as her viciousness and vindictiveness, is frightening.
The messes made by Bush in Iraq, FEMA, the Dept. of Justice, and the U.S. economy came from his willingness to listen to (and reward with jobs) the people he liked and agreed with, while ignoring (or firing) the people he didn't like.
For Palin, Trooper-gate, the mass firings after she became mayor, and just about everything else I've read about her demonstrates that, given power, she would do the same as Bush did AND MORE.
She lacks not only the skills and experience to lead, but the temperament as well.
