Right. I sort of wonder what folks think Hillary could've said when asked about Bush's arrogation of power to the executive: "It's been great for this country, I'm glad he set me up to be dictator?" She said she'll review it, and, if appropriate, relinquish bits and parts. I doubt she'll judge it appropriate (just like I doubt any of the other candidates, save maybe Ron Paul or Chris Dodd, would find it appropriate). The incentives for the president are to maximize power. That's why Congress actually has to assert itself here, not look to the goodwill of some future executive to do it for them.
