The November elections surely won’t end the nonstop, eight-year political war over the shape of the U.S. healthcare system. But the ballot results likely will determine whether the changes driven by the Affordable Care Act continue in the same direction or the system returns to its less-regulated, pre-ACA contours.

Heading into this week’s Democratic National Convention, Hillary Clinton has promised to preserve and expand the ACA’s coverage expansions and delivery system reforms. Donald Trump, who accepted the Republican nomination last week, says he wants to repeal them, without offering much detail about what he would put in their place. The fate of the victor’s proposals, however, will depend heavily on the partisan makeup of Congress.

The clearest scenario is if Trump wins and his party retains control of both the House and the Senate, which would enable conservatives to repeal or roll back the ACA and implement at least some of the proposals outlined in the GOP party platform and the recent House Republican leadership white paper on healthcare. But there are divisions even among conservatives over issues such as Medicare restructuring and how to help Americans afford health insurance. And Senate Democrats almost certainly would use their filibuster power to block major ACA changes.

If Clinton wins and Democrats take control of both the Senate and the House—which is considered unlikely—she might be able to push through proposals such as increasing funding for federally qualified community health centers. But Senate Republicans also could use the filibuster to foil her. In the more likely scenario of a Democratic-controlled Senate and a GOP-controlled House, it’s not clear how much Clinton could achieve through the legislative process.
