One of the worst things about the Bush presidency, which many conservatives will agree with liberals, was his management style. He surrounded himself with old friends and insiders, valuing loyalty above competence. And it's been a disaster.

Hillary Clinton seems to come from that same school:

Mrs. Clinton showed a tendency toward an insular management style, relying on a coterie of aides who have worked for her for years, her aides and associates said. Her choice of lieutenants, and her insistence on staying with them even when friends urged her to shake things up, was blamed by some associates for the campaign’s woes. Again and again, the senator was portrayed as a manager who valued loyalty and familiarity over experience and expertise.

While the jury is still out on Barack Obama's management competency, his quick handling of the Samantha Power "monster" incident shows that he's not afraid to pull the trigger on close advisers when the situation calls for it.
