Rogue donors not ready for Hillary?

Politico reports:

Hillary Clinton is facing the beginnings of a backlash from rich liberals unhappy with her positions on litmus test issues and her team’s efforts to lock up the Democratic presidential nomination before the contest starts.

Elizabeth Warren says she’s not running, but donors are pledging big money to get her to reconsider. Joe Biden, Martin O’Malley and Jim Webb have found polite and occasionally receptive audiences among potential sugar daddies. Even Bernie Sanders has support from some wealthy donors.

Questioning the inevitable candidate in the Democrat party.
