Hillary has pretty much always been a straight Democrat. Whatever general platform the DNC advances, hers always seem in near lockstep. So essentially lip service to the left while instituting slightly right of center policies.
That said, I think that is honestly more appealing to more people. There has been a long history, abroad but especially in America, of the radicals forcing an issue into national consciousness and then the more moderate wing advancing a watered down version and breaking the back of the more extreme movement to secure temporary power.
