Congress takes up health care again − and impatient voters shouldn’t hold their breath for a cure

As the bell struck midnight on Jan. 1, 2026, time ran out on Obamacare subsidies for over 24 million Americans^[1]. These subsidies, propped up through various legislative packages over the years, lowered the health insurance costs for Americans on the Obamacare exchange.

Following the expiration of these subsidies, health insurance premiums are skyrocketing^[2] for around 90% of Americans who use health insurance from the exchange. For many Americans, the new year means a choice^[3] between paying exorbitant costs or taking the risk of no health insurance at all.

But unlike other policy challenges that Congress may face in 2026, the expiration of health insurance subsidies was not unexpected.

The extension of health care subsidies was the pivotal disagreement that ultimately led to the longest government shutdown^[4] in U.S. history in the fall of 2025. Democratic members, in support of extending the subsidies, faced off against the majority party in Congress: Republicans who wanted a short-term legislative fix that did not fund subsidies.

Republicans ultimately won the shutdown battle^[5]. And while Democrats attempted a last-gasp vote in December^[6] to reform and extend health care subsidies, the health care debate was yet again punted into the next year.

Congress has reconvened, and Democratic members – joined by four Republican members – used the best possible procedural tool at the minority party’s disposal, the discharge petition, to force congressional leaders to allow votes on an extension of Obamacare subsidies^[7] during its first week back in session. But overcoming congressional leadership is an immense challenge: Even if the House is successful, Senate Republican leadership has made clear^[8] that there is no future for the legislation in that chamber.

The challenge of passing meaningful solutions to rising health care costs is not unique to this year or to this Congress. It has been a decades-long argument among lawmakers that shows no sign of being resolved.

Why is it so hard for Congress to lower the cost of health care for the people who sent them to Washington?

Like many policy problems, partisanship is partly to blame. But the sprawling complexities of the American health care system pose a particular challenge to members of Congress. As my own research finds^[9], the outsized power and resources of congressional leaders means that for Congress’ most intricate issues, rank-and-file members do not have the time, resources or, frankly, the interest to dedicate to meaningful problem-solving.

Government ‘dips its toe’

Americans face some of the highest health care costs in the world^[10]. Lawmakers on both sides of the aisle have long campaigned on addressing exorbitant costs and equitable access.

Progressive politicians proposed the idea of national health insurance as early as the 1900s, but efforts were limited to women and children^[11], and any policy successes were moderate and temporary.

Following the Great Depression and the advent of Social Security in the 1940s, Congress had warmed to the idea of the federal government providing social services. But attempts at widespread health care coverage^[12] failed to gain traction.

During the 1950s, as Americans began to expect more services from their tax dollars, formal coalitions formed in support of, and in opposition to, government-supported health care. Workers and unions, bolstered by Congress and the Supreme Court^[13], used the power of collective bargaining to push for employee benefits such as health insurance. Doctors and medical providers, enjoying their current – and profitable – position, coordinated campaigns against^[14] national health insurance proposals.

The tension held until 1956, when the government dipped its toe into federally funded health care, enacting the first “Medicare” government-funded program for dependents of the armed forces^[15].

In the private sector, employee demands and employer tax incentives^[16] led to a convoluted web of employer-based insurance programs. But for many Americans, particularly the retired and elderly and those with low-paying jobs, there remained few, if any, insurance options available.

Enter: Medicare and Medicaid

In the 1960s, under Democratic President Lyndon Johnson’s vision for a “Great Society^[17],” and with a bipartisan vote in Congress, the federal government took the greatest step forward in providing federal health assistance for Americans: Medicare and Medicaid. The programs helped with the cost of health care via federal health insurance for those who were elderly and low-income, and they ushered in a new era of federal health policy.

This was a watershed moment for policymakers. With health care coverage now under the umbrella of the federal government, domestic policymaking responsibility expanded^[18] to match. For lawmakers, this meant not only new debates but also new federal agencies, new congressional committees, new lobbying firms and new interest group coalitions.
