What's so disappointing about Warren is that she's absolutely right and had no reason to ever stop talking about these issues. She understands the relationship between capital and racism, she understands how wealth inequality hurts everyone despite hurting different groups disproportionately, and she understands how you can't have freedom in a system where the primary motivator is profit. She understands that simply being pro-choice doesn't mean anything when you support the ability of private health insurers to deny women coverage for abortions, which Hillary supporters never understood. She and Bernie are the only ones running who have even said out loud that these problems are systemic and aren't going to magically go away once Trump is out of office.
So the fact that she then departs from that message every few weeks to tell easily falsifiable lies about not taking money from PACs, or saying Bernie told her women can't be president despite him being the one begging her to run in the first place, or saying that it was okay for her to market herself as POC because her grandfather had "high cheekbones" or whatever that dumb racist shyt she said was, it not only craters her campaign but it delegitimizes the very real and very salient points she makes about everything else along the way. No one can refute anything she says about the failure of private health insurance or the relationship between home ownership and racial wealth inequality. She was on her way to surpassing Bernie in the polls. And now she's about to get passed up by Bloomberg, who doesn't give a shyt about anything, has no coherant vision for the future, and is literally just an accessory to Republicans. That's a loss for everyone, even if you don't support her.
