I’m not really sure what you’re talking about.
Sure, Bernie’s radical thinking put him at odds with the establishment and might not get him elected in the end, but he’s not looking for external scapegoats. Yeah, it’s him vs the establishment and that includes being at odds with moderates (what ‘other’ moderates? he’s not a moderate). You could fault him for being at odds with progressives like Warren, sure. But all in all, that’s the price of being consistent with your principles.
I didn’t say that Sanders should get credit for universal healthcare. It’s not like he invented it. But he was supporting it since way back when Warren was on the other side of the isle. He should get credit for putting universal healthcare on the political map and for consistently promoting it.
Warren at some point decided to adopt that position and didn’t bring anything new to the table. There’s no patriarchy involved. If Warren had at least a consistent political compass, I’d give you that, but she’s about the same age as Sanders and when Sanders was supporting the same ideas that he’s putting in the spotlight now, Warren was a hardcode corporate stooge and that’s about all there is to it.
If there are two progressives at the table, I’ll always pick the one that’s no a progressive because they happened to change their mind one day. There’s nothing wrong with that (per se) but if there’s someone who is on the same side AND they’ve always been there, it would go with my preference.
