If I could only ask one question of the 20-odd candidates vying for the Democratic nomination for President at the next debate coming up right here in Detroit, Michigan, here's how I would word it. I've customized it for each of the five major candidates (apologies to the rest of them):
Preface to each of the candidates:
"Earlier this month, oral arguments were heard by the 5th Circuit Court of Appeals over a lawsuit against the Affordable Care Act filed by 20 Republican Attorneys General and fully supported by the Trump Administration.
"If the plaintiffs are successful and the ACA is struck down entirely, up to 20 million Americans would find themselves without healthcare coverage and tens of millions more with pre-existing conditions would lose critical protections, while states would lose hundreds of millions, or even billions of federal funding.
"Every Democratic candidate has come out in favor of significantly expanding publicly-funded healthcare coverage to some degree or another. Some want to build upon the Affordable Care Act. Some want to add a public option. Some want guaranteed universal coverage, and some are demanding universal single payer healthcare for everyone in the United States.
UPDATE 8/20/19: I originally posted this in late June. Since then, there have been several important developments: Joe Biden and Kamala Harris have formally rolled out their own official healthcare overhaul plans, with Harris splitting off from Bernie Sanders' fully-mandatory "Medicare for All" bill to her own variant, which keeps the name but has similarities to "Medicare for America". Also, Eric Swalwell and John Hickenlooper have dropped out (ok, not every development was major).
I've updated the post to reflect these changes, while also updating the table graphic, which I've also simplified by removing Swalwell, Hickenlooper and most of the other bottom-rung candidates. I'm keeping everyone who's qualified for the September/October debates as of this writing, plus Tulsi Gabbard, Jay Inslee and Tom Steyer, each of whom is partly qualified.
