How about an inter-state compact where states can willingly join a group and adopt common set of laws/regulations. If California, New York, Illinois and Massachusetts join this group, you already have 75-80M population with more liberal states to follow. This group can also be used to advance other liberal agenda on issues pertaining to energy, climate or agriculture. Of course, conservative states can do the same to advance conservative agenda to bypass gridlock in DC. But nothing wrong with that either. We will have some sort of real world A/B testing between the two groups and see which policies work better for a given problem. The advantage of a compact of states is that it enables significant weight behind a proposal, which would be hard to ignore for the companies (eg. fuel efficiency standards might be ignored for MA alone, but will be hard to ignore for market controlling 30-40% of the population).
