President Donald Trump’s standing among Republican voters is showing signs of strain less than a month before the 2026 US midterm elections, with polls suggesting some GOP voters may cross party lines to support Democratic candidates.
The shift is particularly notable in several traditionally Republican states where Democratic Senate candidates have moved into competitive positions. Recent New York Times/Siena polling found Democratic candidates either leading or running close to Republicans in states including Texas, Ohio, Iowa and Kansas.
A growing share of Republican voters also appears willing to support Democrats in individual Senate races. The polling cited in the latest analysis found Democratic candidates attracting between 9% and 16% of Republican likely voters in five closely watched states — Alaska, Iowa, Kansas, Ohio and Texas.
Kansas has emerged as one of the clearest examples of the changing political landscape. Democrat Adam Hamilton was tied with Republican Senator Roger Marshall at 45% among likely voters in the Times/Siena survey, despite Kansas being one of the country’s most reliably Republican states.
Hamilton’s strength is being driven partly by crossover support. The survey found him attracting 16% of registered Republicans and 10% of self-identified Republicans, while Marshall drew only a small share of Democratic voters.
Other Democratic candidates are also attracting meaningful support from Republicans. Iowa Democrat Josh Turek has recorded crossover support in multiple polls, while former Alaska congresswoman Mary Peltola received 13% of registered Republican support and 9% among self-identified Republicans in the Times/Siena survey.
In Georgia, Democratic Senator Jon Ossoff has also attracted around 10% of self-identified Republicans in recent high-quality polling. Democrats in North Carolina, Ohio and Texas have similarly averaged around 9% support among Republican voters in recent surveys.
The trend is even more pronounced among Republicans who do not identify with Trump’s MAGA movement. Recent Fox News polling showed Democratic candidates winning more than one-fifth of non-MAGA Republican voters in several competitive Senate contests, including North Carolina, Texas, Ohio and Iowa.
That could prove significant because the 2026 Senate map is increasingly extending into states Trump won in recent presidential elections. CNN reported that its battleground list has expanded to include Kansas, while Ohio, Alaska and Texas have also become increasingly competitive.
The numbers, however, do not guarantee a Democratic victory. Pollsters have underestimated Republican support in some recent presidential elections, raising the possibility that Democratic candidates could be overstating their current strength if GOP voters who are harder to reach by surveys turn out in large numbers.
Midterm polling also carries its own uncertainties, including turnout and the motivation gap between voters who strongly support a candidate and those who are only leaning toward one.
Still, the current Senate map represents a significant change from earlier expectations. CNN’s analysis has described the contest for Senate control as unusually tight, while recent polling has placed several Republican-held seats within striking distance for Democrats.
The pattern echoes the 2018 midterm elections, when Democrats also won sizeable shares of Republican voters in several states during a strong election year for the party.
For Trump and Republican candidates, the immediate challenge is therefore not simply turning out the party’s traditional supporters. They must also prevent dissatisfaction among Republicans and non-MAGA conservatives from becoming enough crossover support to alter close Senate contests.
With Election Day approaching on November 3, the size of that crossover vote could become one of the defining questions of the 2026 midterms.
