Sanders: Sinema Is Just a 'Corporate Democrat' Who 'Sabotaged Enormously Important Legislation'

When asked if Sinema has the guts to take on powerful special interests, Sanders replied, “No. She doesn’t”

@RollingStone I think the word Sanders is looking for is Sinema is a corporatist or a corporate independent. It would be amusing to see how much Sanders attacks the Democratic party -- which is the only institutional force we have to thwart Republican efforts to destroy the regulatory state -- if it were not so dangerous.
She's got the guts to tell voters FU and then "take on" those special interests as donors !
@RollingStone a class action suit by her swindled donors seeking a refund would be a fun development.
@RollingStone Sinema has been a Republican since day one. I heard a discussion where the guest had summed it all up very nicely: "...she is a 'party of one.'"
@RollingStone once elected, Sinema behavior shows just how little power constituents really have in government when compared to corporations and donors. We have to change voter power or we will get more Trumps (from disgruntled ignorant angry voters) or Sinemas (betraying politicians). All dysfunctional.
@RollingStone How could she even take them on from inside their pockets?
@RollingStone For real... As soon as Sinema realized she no longer has any power, she becomes an independent... All I can say is that the Democratic party is better without her...
