Democrats are entering the final weeks of the 2026 midterm campaign with several encouraging political indicators, but a new analysis warns that a familiar problem could complicate their expectations: Republican voters who are difficult for pollsters to reach.
With control of Congress at stake November 3, Democratic candidates have expanded their campaign efforts into traditionally Republican territory while GOP strategists adjust their spending priorities and attempt to mobilize President Donald Trump’s supporters.
However, National Review senior writer Noah Rothman argues that Democrats should be cautious about interpreting favorable polling as a complete picture of the electorate.
His concern centers on voters who supported Trump in previous elections but rarely participate in political surveys.
Those voters could be underrepresented in current polling, potentially creating an inaccurate picture of Republican support.
The warning comes as Republicans confront unfavorable political conditions in several competitive congressional races.
A Reuters examination published October 7 found that Republican candidates in 41 of 62 competitive House and Senate contests had either broken with Trump on particular policy questions or attempted to create some distance from him.
That represents approximately two-thirds of the GOP candidates examined.
The disagreements generally involved specific issues rather than outright opposition to the president’s broader agenda.
In Michigan, Republican Senate candidate Mike Rogers recently called for ending the administration’s tariff dispute with Canada, arguing that the trade restrictions were hurting businesses and consumers.
Rogers also urged an end to the war with Iran after previously supporting the military campaign.
That said, even CNN is noting that Republican and MAGA enthusiasm heading into the midterms has matched that of Democrat voters, further complicating the party’s effort to win back Congress:
Should note the GOP is in its best position on party registration (i.e. not polls) going into a midterm in 20+ years.
In total, the Dems have not gained ground since 2024 in key swing states (AZ, NV, NC, or PA).

Meanwhile, Republican campaign organizations have been reassessing their investments in competitive states.
Democrats have responded by expanding their list of targeted House districts, including constituencies where Trump performed strongly in 2024.
The developments have encouraged speculation about substantial Democratic gains, although campaign spending decisions and candidate positioning cannot establish how voters will behave on Election Day.
Rothman’s central argument is that polling organizations may be overlooking an important segment of the Republican electorate.
The problem is particularly relevant in rural communities, where some surveys have encountered unusually low response rates.
National Review highlighted concerns raised by State Navigate executive director Chaz Nuttycombe about polling participation in Iowa.
Nuttycombe questioned whether the unusually small number of rural respondents could distort estimates of Republican support.
He suggested that polling results showing dramatic Democratic improvements in rural areas should be treated cautiously until actual votes are counted.
Pollster G. Elliott Morris raised a related concern about respondents who devote little attention to political surveys.
Morris estimated that differences in survey participation and respondent behavior could potentially produce polling errors of several percentage points.
Importantly, those errors could benefit either party rather than necessarily favoring Republicans.
The polling concerns come alongside evidence of a Republican turnout challenge.
Democrats are LOSING the voter registration war in every key battleground.
As political pros will tell you, these numbers are much more important than public polls. https://t.co/6d3dmg1hIp

A Reuters/Ipsos survey released Thursday found that 48% of voters who supported former Vice President Kamala Harris in 2024 described themselves as very enthusiastic about voting in November.
Among voters who supported Trump, only 30% expressed the same level of enthusiasm.
The 18-point difference raises questions about whether Republicans can reproduce the participation levels that helped Trump return to the White House.
The survey included 4,506 American adults and was conducted over six days.
Enthusiasm, however, is not the same as actual turnout.
Some voters who express limited excitement still participate, while others who report strong enthusiasm ultimately stay home.
Democratic campaigns have increasingly targeted districts that were previously considered reliably Republican, though it’s not at all clear if the party will be successful, especially given it’s huge money deficit.
Reuters reported Thursday that Democratic organizations were directing available resources toward congressional contests in Kansas, Oklahoma, Texas and Virginia.
Republicans, meanwhile, are attempting to defend their congressional majorities while emphasizing the administration’s economic and immigration policies.
