When Hillary is right, this stubbornness is commendable. But when she is wrong, it is frustrating to her supporters and infuriating to her advisers.
But there's another reason for her stubbornness. Hillary, for all of her vaunted independence, depends on gurus to guide her every move. She falls under their spell and, while thus mesmerized, she believes they can do no ill or make no mistake.
Hillary wouldn't compromise on health care because her guru-du-jour Ira Magaziner told her not to do so. She wouldn't release the Whitewater records because her former mentor, White House Counsel Bernard Nussbaum, advised against it. She wouldn't back off her support for the war partially because the generals to whom she had come to listen and admire while serving on the Armed Services Committee warned that it would lead to a disaster. Combine that with the flawed guidance of her pollsters and you see why Hillary is stuck.
Sometimes the gurus are right (as on Iraq). Sometimes they're wrong. But Hillary can't tell the difference.
That's a key reason why she shouldn't be president.
