Removing liberal plutocrats from the dem constituency would still leave that constituency far broader than the reps'.This is kind of funny since Weiss was one of the far left Wall Street boys who lapped up the money but supported high taxes on upper middle class earners. Warren has fired a shot at one of the democrats' most important constituencies, the big money limo liberal crowd.
She is far out of step with her party, but will get only positive media coverage, unlike say a Michelle Bachmann, who is basically her right wing analog.
