Democrats Maintain Edge in Congress Fight as Trump Poll Ratings Slide — NBC Survey

June 18, 2026 4 min read

A fresh NBC News survey shows Democrats retain a narrow advantage in competitive Congressional districts heading into the final stretch of the election cycle, even as former President Donald Trump's personal approval ratings remain deeply underwater with American voters.

Poll Findings Show Competitive Battleground

The survey, conducted across multiple battleground states, found Democrats holding a slim but consistent lead in House and Senate races that will determine control of Congress. The margin sits within the polling error range, leaving Republicans with a realistic path to flip several seats. NBC News researchers noted the results track closely with other recent national surveys showing competitive dynamics in suburban and independent-leaning districts.

What stands out in the data is voter intensity. Democrats have opened a meaningful lead in enthusiasm among core supporters, a factor that typically drives turnout in midterm elections. Republicans have struggled to match that energy despite consistent messaging on inflation and crime. The NBC News Poll, conducted in partnership with The Center Square, surveyed registered voters across key states where control of the House and Senate remains genuinely contested.

Trump Marks Drag on Republican Appeal

The same poll delivered uncomfortable reading for Trump and his endorsed candidates. Ratings for the former president have dipped further into negative territory, with disapproval outweighing approval by a significant margin. The survey found Trump underwater even in states he won during the 2020 presidential election.

This creates a complicated dynamic for Republican campaigns. Several party strategists have privately acknowledged that Trump's presence on the ballot—either directly or through his chosen candidates—serves as both a fundraising tool and a liability. Trump-backed candidates have won most Republican primaries, but the general election presents a different electorate where moderate and independent voters hold disproportionate influence.

The Suburban Voter Shift

Pollsters identified suburban voters as the decisive group in dozens of competitive districts. These voters, many of whom backed Republican candidates as recently as 2020, have moved away from the party in successive elections. Economic concerns remain their top priority, yet their views on democratic norms and institutional integrity continue to shape ballot decisions. NBC News reported that suburban women, in particular, expressed deep skepticism toward Republican messaging on abortion and election security.

The NBC News Poll found that among suburban voters who described themselves as politically independent, Democrats held a 12-point advantage on the Congressional ballot question. Republicans need to win a substantial portion of this group to reach the 218 seats required for a House majority.

Economic Anxiety Shapes Voter Priorities

When asked about the most pressing issues facing the country, respondents ranked inflation and household costs at the top of their concerns. Gas prices, grocery bills, and housing affordability dominated responses across income levels and party affiliations. This economic anxiety creates an opening for Republicans, who have made cost-of-living their central campaign argument throughout the year.

Yet the poll suggests the political benefit from economic grievances has been partially offset by other factors. Voters expressed frustration with Congressional Republicans for failing to produce significant legislation despite controlling the House for two years. Approval ratings for Congress remain near historic lows, with both parties receiving poor marks from majorities of those surveyed.

Battleground State Landscape

The NBC News survey included oversamples in states that will determine Senate control, including Nevada, Arizona, and Georgia. Democrats currently hold slim Senate majorities, and the map presents roughly equal opportunities for both parties. Republicans need to net three seats to reclaim Senate control if they lose the White House, or four seats if a Democrat wins the presidency.

In Nevada, the poll showed a tight race with neither candidate holding a decisive lead. Arizona's Senate contest featured a rematch that has drawn significant national party investment. Georgia's race has attracted enormous attention following its pivotal role in the 2020 and 2021 elections. NBC News researchers noted that early voting patterns in all three states suggest turnout will be higher than typical midterm averages.

What Happens Next

With fewer than six weeks remaining before Election Day, both parties are accelerating their spending and ground game operations. Early voting begins in several states within the next month, making voter contact operations the immediate priority. Campaigns are targeting low-propensity voters who historically sit out midterm elections but could prove decisive in tight races.

The NBC News Poll represents a snapshot in a volatile political environment. Economic indicators, international events, and any late-breaking developments could shift voter priorities before ballots are cast. Political analysts will be watching subsequent surveys for movement in the Congressional generic ballot and Trump approval ratings, both of which serve as leading indicators for election night outcomes.
