True, Ace did incorrectly say this didn't help the poor. However, that's about the only "good" (and I use the term loosely, because the help it provided came in a wrong form and in a wrong way) thing that the ACA did. By far, the ACA has done and continues to do more harm than good, and this was its design, and we knew it from the beginning. We knew millions could, and likely would, lose the insurance plans they liked. We knew many would lose their doctors. We knew prices would continue to increase, and that many would have to pay a lot more money because they were forced to buy services they didn't want and didn't need.
We also knew that we could have found other ways -- that didn't make insurance policies worse for millions of people -- to help the people who didn't have insurance, and, to some extent due to that fact, didn't have good medical care, including simply raising taxes to pay for Medicaid expansion. I'd choose that over increasing the cost and scope of health insurance, and massively increasing government control over the industry.
The final thing we've known all along that I'll mention is that Obama has been lying about this from the beginning. He knew his promise that people would get to keep their coverage was false, when he said it (I know this simply because, without talking to any experts, *I* knew it, through simple deduction; it's inconceivable that he didn't know it, as he isn't a dummy and has lots of experts to talk to, and all of them knew it).
He also continues to lie every day, saying Republicans want people to not have health care, or that anyone has gotten health care for the first time in their lives because of the ACA. Both of those lies are insane. There's not a serious way to make either of them into even plausibly true. But he keeps saying this shit anyway.
As to the latter, not a single person ever has gotten health care for the first time due to the ACA, unless you're going to make the case that because of the ACA, some couples had babies that they otherwise wouldn't have had. Otherwise you're SOL on this claim: every single person in the U.S. not only had access to health care before the ACA existed, but actually got health care, even if it was self-care. This is part of the fundamental conceit of Obama and his policies: you equate two different things (health insurance vs. health care) and convince people that without the former, the latter doesn't exist, and make the case that only government can provide the former, and hence, the latter. It's insanely stupid, but I guess it works on a lot of people.
