The Obama admin promised groups of people free, or heavily discounted, unfettered access to the US healthcare system … paid for with OPM. In addition, people were promised no lifetime caps, guaranteed issue, no risk adjustments, kids are kids until 26, sign-up after you need treatment, and more. The Fountain of Youth is likely in there somewhere.
Now the GOP is tasked with essentially reneging on a political promise that could never be kept and should never have been made. Not unlike other Ponzi and OPM schemes.
