OK, here it is. I've linked to a PDF with the full legislative text at the bottom of this blog entry; here's the summary version, with some notes:
TITLE I—ESTABLISHMENT OF THE UNIVERSAL MEDICARE PROGRAM
Establishes a Universal Medicare Program for every resident of the United States, including the District of Columbia and the territories. Guarantees patients the freedom to choose their health care provider. Provides for the issuance of Universal Medicare cards that all residents may use to get the health care they need upon enrollment. Prohibits discrimination against anyone seeking benefits under this act.
OK, so it apparently would cover undocumented immigrants, and every doctor/hospital/clinic/etc. would be required to participate, with anyone in the country being covered by any healthcare provider nationally.
UPDATE: I've expanded the second half of this entry.
A week or so ago, I took a good look at Bernie Sanders's Single Payer healthcare proposal and was, as I put it, "beyond disappointed" due to it's lack of detail, and naiveté about not only the political realities of trying to get such a plan through (which is the biggest issue that Sanders supporters insist can be overcome through a "political revolution" etc etc), but also due to the sheer mountain of legal, economic, infrastructure and logistical headaches that would have to be navigated.
The irony is that, for me, the math behind such a plan (ie, how much it would end up saving people overall in terms of actual dollar savings as well as reduced administrative overhead, greater efficiency, etc) was something which I didn't even get into. I was operating on the assumption that, while the specifics would obviously jump up and down here and there, the numbers were generally in the right ballpark. HOWEVER, according to Emory University expert Kenneth Thorpe (who's actually a strong single-payer advocate who has authored several SP plans himself), that may not be the case whatsoever.

I've been debating (pun intended!) how to handle the ongoing 2016 Presidential primary season when it comes to the ACA. While the ACA has barely come up at all in either of the first 2 GOP debates, it's almost certainly going to start popping up sooner or later (and I'll be stunned if it isn't a major topic at the Democratic debates).
I'm gonna try doing an occasional "Candidate Roundup" with the latest ACA-related happenings when it comes to the various candidates...and there have been three major developments this week:
