Donald Trump certainly seems to think the news of premium hikes will work in his favor, though his criticism in reaction to news has revealed more about the limitations of his own policy knowledge than anything about how he’d fix the problem. On Tuesday after the administration’s announcement, Trump appeared to confuse “Obamacare” for an actual insurance plan, and seemed unclear as to how his employees are covered.

“We don’t use Obamacare,” Trump said to Fox News. It is unclear, based on these comments, if Trump knows what a double-digit premium increase for people on the insurance exchanges even means.

Assuming a charitable explanation of his remarks, Trump’s main difficulty, and the one that his party also faces in many down ballot races, is that even with the bad news, it might be hard to recapture the political urgency of health reform—and repeal—as a critical campaign issue in 2016. For one: The administration’s announcement is a mere formalizing of increases many people familiar with the industry predicted throughout the year.

If Trump is indicative, Republican politicians don’t have the language to capitalize on some of the weaknesses of the law right now. Over the past two years, neither their calls for blanket repeal of Obamacare, nor the coverage of historic gains in insurance coverage, have meaningfully altered public opinion one way or the other.

Perhaps the reason why it’s so hard to move public opinion either way is because many of the most publicized changes don’t have real measurable impacts on the lives of most voters right now. Only a small sliver of the population is enrolled through the exchanges, and most people in the country are covered through their employers, where premiums have risen at rates similar to previous years.

Of that small sliver of people in the exchanges, over 80 percent of enrollees are shielded from the true costs of insurance premiums by government subsidies and cost-sharing. The federal government will protect most Americans from the real financial impacts of a spike in premiums, and only between five and seven million people will bear the full sticker shock of Obamacare premium hikes. That’s no small number, but spread across states, it’s certainly a tough demographic to target in a presidential campaign, and probably too diffuse to target for local and congressional races. Additionally, most people with subsidized coverage who are directly threatened by the loss of Aetna or other major insurers won’t have to go shopping for new plans until 2017.

A recent Kaiser Family Foundation tracking poll suggests that the future of the Affordable Care Act isn’t even the top health care issue for registered voters, but that finding comes with a few grains of salt. Sixty-six percent of those polled viewed the future of Medicare as a non-exclusive “top priority,” with an equal proportion viewing access and affordability of health care as such. Both the future of the Medicaid program and affordability of prescription drugs rank ahead of the integrity of the ACA law itself, and the opioid epidemic, access to reproductive health services for women, and Zika round out the list of important concerns for voters.
