The Fragile Coalition: How Medicaid Cuts May Backfire on Republicans

As the Republican party crafts their One Big Beautiful Bill, warnings are being sounded about the potential fallout of Medicaid cuts. Sen. Josh Hawley has emphasized that voters, particularly those brought into the party by President Donald Trump, rely heavily on social insurance programs. A closer look at counties with the biggest Republican swings in the Trump era reveals a pattern: Trump's gains were disproportionately among lower-income voters, many of whom rely on Medicaid. In counties with high Medicaid enrollment, Trump gained an average of 17 percentage points in margin over the party's 2012 performance, more than double his average gain in counties with low Medicaid enrollment rates.

Key Takeaways:

• The Republican coalition has changed significantly since 2012, with a large portion of the well-educated, suburban electorate now voting Democratic at the federal level.
• Trump's 2016 campaign yielded major gains for Republicans among voters inclined toward expanding the social safety net, particularly among voters who supported universal health care but opposed amnesty.
• In counties with high Medicaid enrollment rates, Trump gained an average of 17 percentage points in margin over the party's 2012 performance.
• Many House Republicans represent districts with high Medicaid enrollment rates, opening new political vulnerabilities, including several battleground Republicans who won only narrow victories in 2024.
• The KFF survey found that 69% of Republicans on Medicaid and 62% of low-income Republicans are at least "somewhat worried" about cuts to the program.
• The Republican coalition is fragile, and Medicaid cuts may push lower-income voters they have picked up in the past three cycles back to the Democrats.
• The durability of Trump's coalition remains to be seen, and the midterm reaction to his One Big Beautiful Bill will be an important test of its staying power.
