The Biden/Harris platform is actually really good. I say this in spite of Biden being my least favorite of all the main party candidates other than Trump.
I like the healthcare policy. It doesn't eliminate for-profit private health insurance, but it would expand coverage to over 90% of the populace (excluding only illegal immigrants). It would subsidize costs for anyone below 400% of the federal poverty line and create a public option (basically "Medicare for All who want it"), but allowing the public option to negotiate prices.
