There is a spectrum from Socialist to Freedom Caucus on healthcare. Their positions are all the way from single-payer for all to no government payment and not even any regulation of insurance companies. But no single group has the votes to change anything.

We have explored a coalition between normal Republicans and The Freedom Caucus: Doesn't work because they are diametrically opposed. But what about a coalition between Democrats and a few Moderate Republicans from Blue states? Are there enough votes there to lower the ACA income limit down to each state's upper Medicare limit? Those brave Republicans would get a lot of credit in their states for actually fixing a problem. When reelection time comes they could point to it and say they actually did something. Since this is just a numerical value that affects the budget I think you could pass it in reconciliation, avoiding a filibuster. Problem would be the committee heads preventing it from getting to the floors for a vote.

I'm not convinced that the voters actually care about ideology like the Hasturd Rule. (pun intended) They do seem to care about "the do-nothing Congress".
