“Everyday people with good health insurance and ready access to medical care die of preventable diseases,” my friend John, a retired surgeon, wrote me recently. My friend was lamenting a recent article appearing in many Idaho newspapers about the tragic death of a woman with asthma. Her death was blamed on lawmakers who have refused to expand government-run programs like Medicaid to include able-bodied, childless adults.

Government health officials worked diligently this year to improve consumer experience on Healthcare.gov and make sure people know what they are getting for their money when they pick health insurance. But one thing is out of the government’s control: whether doctors and hospitals will agree to accept patients who buy these plans. Surveys and data are limited, so it’s difficult to gauge the extent of the issue, but anecdotal evidence from patients and providers show it is a struggle. Some newly insured patients wonder whether it’s worth paying for coverage they can’t actually use. Even when they do find a provider, reports show they face crippling out-of-pocket costs they didn’t expect.

Republican Matt Bevin’s victory in the Kentucky governor’s race Tuesday highlighted the enduring power of public sentiment about the federal health law to energize GOP voters as the national parties prepare for the 2016 elections. The Affordable Care Act, also known as Obamacare, played a central role in the contest, which Mr. Bevin won resoundingly, 53% to 44%, against Democrat Jack Conway. The Republican pledged to dismantle the state’s health exchange—which earned praise for its relatively smooth launch—and to roll back or modify the expansion of Medicaid under the law.

The Democratic Party has prospered for decades by promising voters entitlements in return for Election Day loyalty. It worked with Social Security and Medicare, and so it was supposed to work for ObamaCare: Pass it and they will come. Instead the Affordable Care Act has become a recurring political catastrophe for Democrats, most recently on Tuesday in Kentucky.

When Congress was debating the Affordable Care Act (ACA), the debate largely revolved around how many people would gain insurance and how the law would impact the deficit, not about how the law would address existing government policies and programs that largely created the perverse incentives. The ACA created several new perverse incentives, unfortunately.

Regardless of whether there is a President Cruz or a President Rubio in January 2017, regardless of the existence or size of a Republican majority in Congress, the so-called Patient Protection and Affordable Care Act (ACA) has failed. The grand vision of an efficient pseudo-market in health insurance under enlightened federal management — the heart of Obamacare — is not coming to pass. Obamacare, meaning the operating model that undergirded the law that Congress passed and President Barack Obama signed with great fanfare — is dead, and it will not be revived. What remains is fitful chaos.

For much of this year, Sara Goodrich of Lakeland has gone without health insurance — despite trying over and over again to complete enrollment on HealthCare.gov. “For the last six months, all of the agents have been telling me something else is the issue. Resubmit here, there’s an address error, it’s your birthday, for some reason, that would affect my application, and I just said, I am trying to follow the rules here, and you guys aren’t helping,’” she said.

Last week, the Centers for Medicare and Medicaid Services released the 2016 premium data for the “benchmark” plans in the states using federal exchanges. … This data, which showed premiums rising an average of 7.5 percent, is useful. But it is limited. We’d like to think that this tells us “how much premiums went up,” but it’s not that simple.

As Marketplace enrollees begin to shop for coverage starting in 2016, the number of insurance choices available to them is changing in some parts of the country. In early 2015, an average of 6.1 insurer groups offered coverage in each state, up from an average of 5.0 in 2014. Since then, some insurers have announced their exit or been required to withdraw from the Marketplaces, most notably a number of nonprofit Consumer Operated and Oriented Plans (CO-OPs) and some larger insurers like Blue Cross Blue Shield of New Mexico. Despite these withdrawals, the Department of Health and Human Services (HHS) recently announced that the average number of issuers per state is increasing slightly in 2016 and that about 9 out of 10 returning Healthcare.gov customers will have 3 or more insurers from which to choose in 2016.
