Cool sarcasm, but again, the ACA further enshrines our broken system and makes universal coverage even less likely to happen. They could have greatly expanded Medicare & Medicaid coverage, but instead went with the Heritage Foundation plan. The Obama/3rd Way practice of pre-compromising is a big part of how we got to where we are now. Where can the right wing party go when the “left wing” party is pushing right wing policies?

This seems less “bOtH sIdEs” and more of a call to reform the DNC, an organization that doesn’t even pretend to promise progressive policies as OP suggests so much as it actively fights against progressive candidates. Also, several of the wins you listed are not so great. The ACA is a Heritage Foundation plan that delays the USA joining the civilized world with universal coverage. The CHIPS act sounds good in principle except it’s corporate welfare that hyper inflated the AI bubble.

There are systemic barriers to a 3rd (or 4th etc) party. No amount of campaigning or organizing will make them viable without systemic change. Attempting to push 3rd parties at the ballot box will, hilariously (in a sad way), benefit the party you least align with.
