Republicans are intensifying efforts to make socialism a defining issue in the final stretch of the 2026 US midterm campaign, attempting to link Democratic candidates across the country with a growing group of progressive and democratic socialist politicians.

The strategy comes as Republicans fight to protect narrow congressional majorities in November while facing voter dissatisfaction over the economy and other issues.

A new national Fox News poll has given Republican strategists another data point for that campaign. It found that 55% of registered voters held an unfavourable opinion of the Democratic Socialists of America, while 30% viewed the organisation favourably.

Those figures describe attitudes towards the DSA rather than voting intentions in individual House or Senate races. They therefore do not establish that Republican attacks involving socialism will determine election results.

They do, however, help explain why GOP campaigns are increasingly trying to make ideological differences within the Democratic coalition part of their closing argument to voters.

Progressive Primary Victories Give Republicans a New Target

The Republican strategy has developed alongside a series of victories by progressive candidates in Democratic primaries.

New York City Mayor Zohran Mamdani, a member of the Democratic Socialists of America, has become one of the most visible figures Republicans use when arguing that the Democratic Party is moving left.

Other progressive candidates have also gained prominence.

In Michigan, Abdul El-Sayed defeated Representative Haley Stevens in the Democratic Senate primary. Republican campaigns have highlighted El-Sayed and other candidates as evidence for their broader argument about the direction of the opposition party.

The DSA itself has also attracted attention with its political platform.

The organisation's 2026 “Workers Deserve More” platform proposes major structural changes to the federal government, including replacing several existing political institutions. Individual Democratic candidates do not necessarily support the entire DSA platform, making the distinction between the organisation's policies and the positions of particular candidates important.

Republican campaign organisations have nevertheless been trying to connect Democratic candidates broadly to the socialist label for months.

The National Republican Congressional Committee began advertising against vulnerable House Democrats following Mamdani's 2025 New York mayoral victory, attempting to associate candidates in competitive districts with his politics and the wider progressive movement.

That approach reflects a familiar campaign tactic: nationalising local congressional races by associating individual candidates with more prominent figures or positions from their party.

Whether it works equally well across different districts is less certain.

Democrats Say the Election Will Be About the Economy

Democratic strategists reject the Republican framing and argue that voters entering the November elections are more concerned about their own finances.

The Democratic National Committee has sought to focus attention on inflation, fuel prices and household costs, arguing that Republicans should be judged on economic conditions while controlling the federal government.

That economic argument could prove significant because Republicans themselves acknowledge that voters remain concerned about prices.

House Republican Conference Chair Lisa McClain recently advised Republican candidates to speak directly about economic difficulties, including high gasoline prices, while tailoring their political messaging to the voters in their individual districts. She also questioned whether simply calling Democrats “socialists” still resonates strongly enough on its own.

The debate therefore extends beyond which party can attach the most damaging ideological label to its opponent.

Campaigns are competing over what voters believe the election should fundamentally be about.

Republicans want voters to consider the ideological direction of Democratic candidates and what a change in congressional control could mean for policy.

Democrats want the contest to function more as a judgment on the party currently holding power and on economic conditions experienced by households.

Those competing approaches are likely to become increasingly visible as advertising spending accelerates.

Trump-aligned political groups have committed more than $130 million to supporting Republican candidates, including substantial spending in competitive Senate and House races. One major focus is Michigan, where Republican Mike Rogers is running against El-Sayed.

Democratic Divisions Add Another Complication

Republicans are not the only ones debating the impact of the Democratic Party's ideological divisions.

Some moderate Democrats have expressed concern that Republican attempts to associate the entire party with the DSA could create difficulties for candidates running in politically competitive districts.

At the same time, progressive Democrats argue that campaigns centred on affordability, healthcare, housing and wages can appeal beyond the traditional ideological labels attached to candidates.

Those disagreements are playing out inside the party itself.

Reuters reported on September 19 that tensions between progressive and establishment Democrats remain visible in several important races, including contests in Michigan, Maine, Texas, New York and Florida. Some candidates who won difficult primaries have yet to receive enthusiastic support from every prominent figure within their state party.

That does not mean those divisions will determine the November results. Midterm elections involve different candidates, electorates and local issues across hundreds of races.

It does mean both parties see an opportunity in defining what Democratic candidates represent before voters make that decision themselves.

Republicans are attempting to transform an election in which the governing party would normally face scrutiny into a broader ideological choice. Democrats are trying to keep attention on prices, economic management and the record of the Republican-controlled government.

With Election Day approaching, the effectiveness of those strategies will become clearer through individual race polling and ultimately through the November results.

For now, the evidence supports a narrower conclusion than the original claim that socialists are “helping” Republican campaigns: Republicans believe Democratic socialism is a useful campaign issue, national polling shows the DSA is viewed negatively by a majority of registered voters in one recent survey, and both Democratic moderates and progressives are debating how much that will matter in November.
