I don't think it's the fact that she stuck by Bill. I think it's the way she did it. She stuck by him and pretended that the women who had previously accused him we're non existent and it was all Lewinskys fault. I think there was something about her not being Tammy Lynnette just standing by here man, but they were a team. However they were never together and all reports were that she despised him behind the scenes. It was seen as trying to pretend to be someone she is not, purely for power.
