Since we seem to have different claims about the popularity of the ACA . . .

here is recent polling from the Kaiser Family Foundation. Highlights:

While health care was not a leading factor in voters’ presidential decisions, President-elect Trump and Republican lawmakers have made it clear that one of their top priorities is the repeal of the 2010 health care law. Americans are divided on what they want to see lawmakers do to the ACA with one-fourth of Americans (26 percent) wanting to see President-elect Donald Trump and the next Congress repeal the entire law while an additional 17 percent want them to scale back what the law does. This is compared to 30 percent of the public who want to see the law expanded and 19 percent who want to see lawmakers move forward with implementing the law as it is.

While President-elect Trump and Republican members of Congress work on a replacement to the ACA, this month’s survey finds that many of the law’s major provisions continue to be quite popular, even across party lines. The notable exception is the requirement that nearly all Americans have health insurance or else pay a fine.

The problem is that people do not understand that the only way to make health insurance available and affordable for everyone is to get everyone into the pool. You can't have the popular provisions without the mandate. It is unseverable. That doesn't fit on a bumper sticker, but it's how the world works.
