In the waning days of this year’s Affordable Care Act sign-up period, the Trump administration declared war on the health law, releasing an executive order that could weaken its requirements and yanking advertisements and outreach off the air.

Those actions appear to have made a difference. Sign-ups for health plans in the states managed by the federal government are down slightly compared with last year. About 9.2 million Americans picked an Obamacare marketplace plan for this year, according to a government report released Friday. Last year, that number was 9.6 million.

The decline by itself isn’t that meaningful, but several snapshots over previous months had shown that sign-ups were on track to overtake last year’s enrollment. It was only in the final two weeks of enrollment, when there’s typically a deadline-driven surge, that the numbers dropped. Fewer than 400,000 people signed up for Obamacare plans over the last two weeks. Last year, more than 700,000 people signed up in the last week alone.

The falloff suggests that Trump administration actions may have confused consumers, discouraged them from enrolling or simply made it easier to forget about the deadline.
