What you SHOULD have gone after Biden for was Anita Hill. It has the double wammy of being racist and sexist, plus it was one of the most disgusting things he's ever done. His ass should have been called out on it from day one. Why no one went after him on it makes no sense to me. Instead, everyone has been sniping at whomever happens to be in second place at any given moment. This ain't Rupaul's best friend race. Go for the fucking throat or what are we even doing here?
Also, if I was Warren, I'd say nothing about the stories until the debate. No matter what she says, CNN is going to ask the question about the "Woman can't win" and "Your campaign pamphlet" thing. If she has receipts for the first, I'd drag his ass halfway across the stage with it. If you don't, then you get to take the high road. Hell, you can even non answer the story with "I won't discuss private conversations we had about the 2020 campaign, only to say blah blah blah."
Historically, when Bernie's been put on the spot for shitty things his campaign has done, he has not reacted how we would define as well. (Remember the exchange in 2016 when his campaign was caught in Hillary's voter data, and it took pulling teeth to get him to apologize?") So I can guaran-fucking-tee you he's gonna get pissy when he's asked about the pamphlet. And, while I know a lot of his supporters really love the grumpy grandpa thing, a lot of voters don't, especially some of the ones he needs to win over to actually get the nomination.
Honestly, the two stories are so perfectly aligned with a lot of the red flags that people have about Bernie. If leveraged correctly, it could be really, really good for Warren.
But, instead, they'll snip at each other, Amy will yell WHY CANT WE JUST GET ALONG, and Biden will skate above it all.
