People keep saying this for some reason lol. What do Corporate Dems have to do with this?
If I were a betting person (which I am not), then I would bet that this was not Warren directly deciding to leak it, it must be one of her staff, one that believes this kind of identity-based smearing will work against Bernie at this point. There is a reason why this was not dropped a year ago, or last month, but rather one day before a debate coming up, and after the latest polls showing Bernie as no#1 in Iowa.
But once again: Bernie endorsed Hillary. He held more than three dozen rallies for her. He wanted Warren to run in 2016. He has decades of history showing that he treats women as equals.You cannot wish sexist Bernie to exist when he does not.
So this is why I lump this attack together with the rest of corporate (otherwise pro-democrat) media-s similar attacks. "Something about him makes my skin crawl / Not a pro-women candidate / Why would AOC endorse an old white guy / etc). It is part of a consistent trend, and it is clearly not working.
