I didn't say acceptable, jeff. I was responding to Gregors 'money over everything' with all politicians remark. For myself, yes, only Sanders has a record on that as well as a break from the neoliberal framing of capitalism as the only way to order society. Warren wouldn't be a disaster but she still believes in capitalism. She just wants a gentler driver of the soul harvester machine. IMO.
That 'perfect being the enemy of the good' is so much nonsense thrown out to dress up incrementalism and failure to voters as some kind of wisdom. All it does is help people rationalize lowering their expectations while the donor class has been looting out the back door.
