# The 2026 Map Keeps Getting Bigger: The Counties That Will Tell You Which Way It Breaks

*A county-by-county checklist for a midterm in which, as one pollster puts it, ‘America is the battleground’*

## In brief

- Republicans are pouring money into Alaska, Texas, Iowa and Ohio as GOP candidates break from Trump over tariffs and the Iran war
- Democratic pollster John Anzalone likens 2026 to the 1994 wave and predicts “accidental members of Congress”
- Harris won 40,000 fewer votes than Biden in Cuyahoga County and 60,000 fewer in Wayne County in 2024
- Texas GOP strategist Matt Mackowiak predicts Tarrant County will be “a bloodbath” for Senate nominee Ken Paxton
- CNN identified about two dozen bellwether counties in six demographic buckets, from Detroit to the Kansas City suburbs

One way to tell a midterm is going badly for the president’s party is to watch where the money flows. A month out from Election Day, Republicans are pouring money into Alaska, Texas, Iowa and Ohio — states that long seemed secure for the GOP — while nervously watching their own candidates belatedly break from President Donald Trump over tariffs, the Iran war and other policies. Democrats, who a month ago were already [leading in the polls as Republicans led in cash](https://rews.cc/a/a-month-out-democrats-have-the-polls-and-republicans-have-th-c8fad1), are now seriously contesting House and Senate seats in blue-collar and rural communities where they have struggled for years. The breadth of the public backlash against Trump’s tumultuous second term is rapidly widening the battlefield for 2026.

John Anzalone, a veteran Democratic pollster who has long focused on races in Republican-leaning terrain, says the erosion of Trump’s support is creating opportunities few anticipated — including Republican-held Senate seats in Kansas, Nebraska and even Mississippi. Whether or not Democrats actually capture those seats, he argues, the sudden emergence of late-breaking threats to entrenched incumbents is a characteristic feature of wave elections, like 1994, when Republicans swept both chambers after Bill Clinton’s chaotic first two years. “This feels more like 1994 and what I mean by that is not the total number of seats \[in play\],” Anzalone says. “But it’s that you feel like America is the battleground.” He predicts the election will produce “accidental members of Congress” — Democrats whose victories almost no one saw coming.

Whit Ayres, a longtime Republican pollster, is less pessimistic but hardly serene. “In this environment, I think we are going to find states in play that we never thought would be in play come in November,” he says.

In polling, Trump’s job approval has generally fallen hardest since he returned to office among the groups that moved most toward him in 2024: young men, Latinos — a trend a [recent battleground survey](https://rews.cc/a/latino-voters-turn-back-to-democrats-before-midterms-as-repu-dce539) also picked up — and non-White voters without a four-year degree. But CNN reports cracks in perennial pillars of his coalition too, including White voters without college degrees, rural voters and traditional Republicans who identify more with the party than with the MAGA movement. Coming out of the election, “I think there is going to be a bunch of narratives,” Anzalone says. “One is going to be that Latinos, African Americans, young people came back to the Democrats. That’s going to be number one. But you are going to see a \[Republican\] bleeding of White working-class voters; and you are going to see a narrowing of the vote in rural America.”

Here is the scale of the potential problem. In 2024, Trump improved his performance over 2020 in nearly 90% of America’s roughly 3,100 counties. Polls now suggest Republicans face the nightmare possibility of the tape rolling backwards: a retreat in counties of all sizes and compositions, in all regions. To map it, CNN identified about two dozen representative counties across six distinct demographic and geographic buckets, whose combined results in House, Senate and governor’s races will document the shifts that decide 2026. Its checklist runs to six groups; three of them give the flavour.

## The urban cores

For all the good polling news, Democrats’ performance in big, heavily minority urban centres remains a question mark: in 2024 Trump modestly increased his vote total in many of them while Kamala Harris’s total plummeted. Wayne County (Detroit) and Cuyahoga County (Cleveland) will show whether Democrats have fixed their turnout problems among urban Black voters — Harris won 40,000 fewer votes than Joe Biden’s 2020 total in Cuyahoga, and 60,000 fewer in Wayne. Alvin Bernard Tillery, a Democratic pollster who studies Black voters, worries the margins still won’t be there: “The data has been there for a while” on the risk of another lacklustre Black turnout, he says, “but people have been ignoring because they want to believe that the old turnout machine is going to hold. And we have seen since 2024 it’s not holding.”

Tarrant County, the majority non-White Texas county anchored by Fort Worth, is true swing territory: it narrowly backed Democrat Beto O’Rourke for Senate in 2018 and spurned him for governor in 2022, and it went for Trump in 2016 and 2024 but Biden in 2020. It now becomes a measuring stick for the unpopularity of Ken Paxton, who beat Senator John Cornyn for the GOP Senate nomination. “Tarrant is going to be a bloodbath” for Paxton, predicts Matt Mackowiak, a Texas GOP strategist who advised Cornyn. “Most of everyone who has a working brain on my side of the aisle thinks Tarrant is gone.”

Hennepin County, centred on Minneapolis, is more affluent and better educated, yet the Democratic vote nosedived there too in 2024. Its results in Minnesota’s governor and Senate races will gauge the intensity of the college-educated backlash — in a place where, as CNN notes, federal agents earlier this year killed two White middle-class residents protesting the massive ICE crackdown in the city.

## The affluent northern suburbs

The well-educated, wealthy, majority-White counties just outside big Northern cities first went blue under Bill Clinton and mostly trended further from the GOP under Trump, though they tilted right in 2024 amid disappointment with Biden’s record. Delaware County, north of Columbus, and Waukesha County, west of Milwaukee, are overwhelmingly White, much richer and more educated than the national average — and two of the largest Northern suburbs still leaning Republican: Trump won Delaware by seven points in 2024 and Waukesha by nearly three times that. The Ohio Senate race (Sherrod Brown) and governor’s race (Amy Acton), and the Wisconsin governor’s race (David Crowley), will test how much Trump’s elevated disapproval among college-educated voters is costing Republicans.

Kent County, centred on Grand Rapids and closer to national averages in income and education — plus even wealthier Oakland County outside Detroit — will send similar signals via Michigan Democrats Abdul El-Sayed (Senate) and Jocelyn Benson (governor). And in Johnson County, in the Kansas City suburbs, where median income exceeds $109,000 and nearly 60% of adults hold college degrees, improving on the eight-point margins Biden and Harris amassed is key to Democrat Adam Hamilton’s bid to end his party’s nearly 100-year losing streak in Kansas Senate races.

## The diverse Sunbelt suburbs

Where postwar suburbs grew around “White flight,” the 21st century produced well-educated, middle-to-upper-middle-class suburbs that are also racially diverse, especially in the Sunbelt; minorities make up about half the population or more, and income and college-degree shares generally beat the national average. These areas have been essential to Democratic competitiveness across the region. Senator Jon Ossoff looks poised to expand on his 16-point 2020 margin in Gwinnett County, with its large Black, Asian and Latino population northeast of Atlanta, and his 10-point edge in demographically similar Cobb County. Emory University political scientist Andra Gillespie says she will be watching whether the Republican decline extends beyond the inner ring to reliably red Atlanta exurbs like Cherokee and Forsyth.

The useful thing about a checklist like this is that it works whichever way the night goes: either the water reaches counties nobody thought it could, or it doesn’t, and someone gets to explain why they ever thought it might. One month out, with [even the grocery-price models pointing the same direction](https://rews.cc/a/cbs-s-midterm-model-has-one-star-the-price-of-groceries-4bc409), both parties are mostly agreeing on the checklist — they just disagree about what it will say.
