Republicans Ran on Repealing Obamacare. Now They're Running Ads Defending Medicaid Cuts They Passed.

Republicans spent a decade trying to kill the Affordable Care Act outright. Now, ahead of the 2026 midterms, they're running ads in swing districts defending their own healthcare record. The shift reflects the politics of what they actually passed.

According to NPR's analysis of YouTube video ads running this midterm cycle, GOP candidates in competitive races are focusing on three themes: Medicaid fraud, rural hospitals, and affordability. NPR reviewed ads for candidates in races rated as toss-ups or lean-one-way by the Cook Political Report, and found messaging aimed heavily at voters over 35.

Rep. Mike Lawler, a New York Republican running in a toss-up district, is one example. According to NPR, Lawler ran ads touting Medicaid reform, saying the law he voted for reduced able-bodied adults on the program. NPR also flagged that Lawler made a false claim that undocumented immigrants can no longer receive Medicaid benefits. They already weren't eligible under "qualified status" rules before the bill passed. Voters deserve the correction.

What the bill actually did

The One Big Beautiful Bill Act, signed into law in July 2025, added new work requirements for Medicaid recipients and cut federal funding tied to state programs and ACA subsidies. The nonpartisan Congressional Budget Office projected about 10 million fewer people will have health insurance by 2034 as a result, according to NPR's reporting.

Enrollment data backs up an early version of that trend. According to the Centers for Medicare & Medicaid Services, there were roughly 3 million fewer people enrolled through ACA exchanges in early 2026 compared to when the bill passed.

Republicans who voted for this bill own that outcome, whether or not they like the campaign math it creates.

Why Republicans are playing defense

Jonathan Oberlander, a healthcare policy expert at the University of North Carolina, told NPR that repealing the ACA was "target No. 1" for the GOP after 2016, and that the failed repeal push contributed to Democrats retaking the House in 2018. He called the ACA repeal effort "extraordinarily unpopular" and "the least popular major legislation of the past 40 years."

Daniel Hopkins, a political science professor at the University of Pennsylvania, told NPR that Republican candidates are getting ahead of the issue this cycle because they know Democratic challengers will hammer them on it. It also means GOP incumbents are implicitly conceding the cuts are a political liability, even as they defend the substance.

Polling backs up why they're worried. According to KFF's April survey, only a third of voters approve of the Trump administration's handling of healthcare costs.

Where Democrats are overplaying their hand

Democratic messaging on this has gotten aggressive, and some of it deserves scrutiny. Senate Finance Committee Ranking Member Ron Wyden and House Energy and Commerce Committee Ranking Member Frank Pallone Jr. released a report claiming 302 clinics and hospitals have closed across 42 states since July 2025, and that nearly 10,000 healthcare workers in 31 states have lost jobs. Wyden called the law a "Big Ugly Betrayal" that produced "the largest health care cuts in American history." Pallone said Trump "meant" beautiful "for the billionaires."

Those are Democratic lawmakers making a political case, not neutral fact-finders, and their numbers come from their own committee reports rather than independent verification in these sources. The advocacy group Protect Our Care similarly cites "over 8 million Americans" losing coverage and points to a Gallup poll showing healthcare affordability topped Americans' list of concerns, above the economy and inflation. That polling data point is legitimate and worth taking seriously regardless of who's citing it.

The strongest conservative counterargument is straightforward: Medicaid work requirements for able-bodied adults without dependents are not radical. Many red and purple states already had similar rules before this law, and proponents argue tying benefits to work or job training encourages self-sufficiency rather than long-term dependency. Fraud reduction and program integrity are legitimate goals, not talking points invented to disguise cuts. Whether the CBO's 10 million estimate materializes as projected, or whether people shift to employer coverage or other options, remains an open empirical question through 2034.

But that argument doesn't erase the enrollment numbers already showing up in early 2026 data from CMS, or the CBO's long-term coverage projection. Republicans voted for a bill with real, foreseeable coverage consequences. Now they're running ads trying to reframe those consequences as fraud prevention and hospital protection. Voters in swing districts like Lawler's will decide in November whether that reframing works, or whether the coverage numbers speak louder than the ad campaigns.
