How Important Is Harris County In The 2026 Election?
Harris County is about to light Greg Abbott's money on fire.
There has never been a November like this one for Harris County.
One in five Texas Democrats lives here. The county judge seat is open for the first time in years. Multiple Texas House seats are within reach. And the governor of Texas, who is sitting on a nine-figure war chest, has personally declared Harris County his top target.
Greg Abbott launched his reelection campaign in Houston. He knows where Texas is decided, and so do we.
The numbers that make Harris County ground zero.
Let’s talk about what Harris County actually means to Texas Democrats, because the numbers are staggering.
18.82% of all Texas Democrats live in Harris County. That means when Harris County turns out, the entire statewide map shifts. When Harris County stays home, the entire statewide map suffers. It’s that simple, and it’s that consequential.
Look at the midterm baseline. In 2018, the last great Democratic midterm in Texas, Harris County delivered at a level that nearly carried Beto O’Rourke across the finish line statewide. And in 2022, even in a rougher cycle for Texas Democrats, Harris County remained the single most reliable source of Democratic votes in the state. Republican turnout in Harris County has weakened over the last decade. Democratic turnout has held.
Here’s what that means for November. If Harris County Democrats turn out at or above 2018 levels, and there is every reason to believe they will, in this political environment, with these candidates on the ballot, we’re looking at somewhere between 750,000 and 850,000 Democratic votes coming out of one county alone. That number doesn’t just help Gina Hinojosa and James Talarico. It forces Abbott to spend money defending ground he thought was safe. It stretches Republican resources across a map they weren’t planning to defend. It changes the math everywhere.
Harris County is the floor on which everything else is built in the effort to flip Texas blue.
Abbott’s $106 million bonfire.
Greg Abbott has $106 million in his campaign account. He announced, out loud, that he plans to spend most of it in Harris County. He wants field directors in all 24 Texas House districts in the county. He wants to knock on the doors of Republicans who don’t vote, turn out voters who supported Trump in 2024, and make Harris County “dark red.”
In 2026. In this political environment. 😂
Greg Abbott has chosen to make his big, expensive stand in a majority-minority county that is nearly 70% non-white, in a year when Hispanic voters are swinging back hard to the left, in a cycle where both he and Donald Trump are underwater in the polls. Democrats are expected to overperform statewide by double digits. He is going to spend eight figures trying to reverse a decade-long demographic tide in a single election cycle.
Good for him.
Not because it isn’t a threat worth taking seriously at the organizing level, but because every dollar Abbott spends in Harris County is a dollar he isn’t spending in the Rio Grande Valley, in the suburbs of Dallas, or propping up vulnerable Republican incumbents in the Texas House. His obsession with this county is, in a very real sense, a gift to Democrats everywhere else on the map, the other 81%.
There’s a reason Republicans lost all three seats in CyFair ISD in 2025. There’s a reason Abbott had to launch his campaign in Houston, instead of somewhere safe. Harris County is a panic move.
Truth be told, Republicans, especially Abbott, panic before every election. They’ve been worried about losing Texas for the last decade. And if you’re familiar with all of the voter suppression bills that have become law in Texas, you get it. They have many reasons to be scared. Democrats have outnumbered them in Texas for many years.
Abbott’s $106 million is real. But the math has not been kind to Greg Abbott in Harris County for a very long time. He might not be able to buy his way out of the hole here.
Dr. Letitia Plummer will be the next Harris County Judge.
Lina Hidalgo is not seeking reelection. For Democrats, that means defending one of the most important offices in Texas, the county judge of the third-largest county in America.
The county judge runs the Commissioners Court, controls the county budget, and serves as the head of emergency management for a region that has lived through Harvey, Imelda, and Beryl. Getting this right matters. Getting this wrong has consequences that show up in people’s lives in very concrete ways.
Democrats got it right.
Letitia Plummer won the Democratic nomination. She came from behind in a runoff against former Houston Mayor Annise Parker, a well-funded frontrunner who led by double digits in the polls just weeks before election day. Plummer closed the gap and won with 51% of the vote. That’s a candidate who built real support from real people, ground up.
Y’all know that I was the biggest Lina Hidalgo fan-girl for the longest time. Knowing that Plummer will be her replacement is the kind of thing that makes you exhale. Maybe after Texas turns blue, Plummer can pick up on some of Judge Hidalgo’s unfinished progressive promises, which Republicans foiled.
Plummer is a practicing dentist, a two-term Houston City Council member, and someone who has spent her career focused on the things Harris County residents actually worry about. She describes herself as the progressive voice this county needs. Given what’s on the line in November, she’s exactly who should be on the ballot.
She’ll face Republican Orlando Sanchez, who won his primary runoff decisively. Sanchez is not a pushover, and Abbott’s money will be behind him. But Plummer is running in a blue county, in a blue year, with a grassroots coalition that just proved it can win a race it wasn’t supposed to win.
Harris County has been in good hands under Lina Hidalgo. It’s about to be in good hands again.
The Texas House seats we can flip.
Abbott said out loud that he wants to oust all seven Democratic state reps currently holding office in Harris County. That’s a cute goal. But they’re all in super-safe blue districts, thanks to the GOP’s gerrymandering, and there’s no amount of money he can throw to change that. He’d literally have to depress the vote substantially to win any of those districts.
What if we flip seats in the other direction?
There are four Harris County, Texas House races worth watching this November closely, ranging from near-certain flips to genuine wave-seat opportunities. Here’s where things stand.
HD138: Tyler Smith vs. Lacey Hull
This is the one. HD138 is majority-minority, with Hispanic residents making up over 41% of the population, Asian residents at roughly 12%, and Black residents at about 10%. It’s been held by Republicans only because of poor Democratic performance in 2022 and 2024, including the temporary rightward shift in the Hispanic vote. That shift is reversing. In 2024, Lacey Hull won 57-43, and Trump carried the district 53-45, but Colin Allred still pulled 47% here in the Senate race, and the district consistently outperforms statewide Democratic averages.
This district is demographically ready to flip. Tyler Smith, a former Biden Presidential Fellow, Obama Foundation Leaders Program graduate, and deputy regional director for Everytown for Gun Safety, is exactly the kind of candidate who can close that gap. Learn more about Tyler Smith here.
HD133: Josh Wallenstein vs. Mano DeAyala
HD133 was the seat with no Democratic candidate in 2024. That’s been fixed. The district is nearly 50% white, with 19% Hispanic, 16% Black, and 14% Asian, a diverse, educated, inner-loop Houston district that Republicans have held largely by default. Josh Wallenstein is a Stanford Law-trained compliance attorney who’s made lowering costs and strengthening schools the center of his campaign. In a strong Democratic year, in a district that’s never really been tested with a serious candidate, this one is worth watching closely. Learn more about Josh Wallenstein here.
HD127: Michelle Williams vs. Charles Cunningham
Michelle Williams is a veteran educator with nearly 30 years of experience and the president of the Houston Education Association, and she’s running directly against the man who helped write the state education policies she’s spent her career fighting. HD127 covers Humble, Kingwood, and Atascocita, and Williams is only the second Democrat to run there in 12 years. But she sees the district’s shifting demographics, with a growing Black and Latino population, as an opening. In a year where public education, vouchers, and HISD’s state takeover are all live issues, Williams is a candidate with a story tailor-made for this moment. HD127 is the strongest “next one up” in Harris beyond the top targets, with over 52% non-Anglo residents, 27.7% Hispanic, and 19.3% Black, making it less likely to be a classic white-flight suburban fortress. Learn more about Michelle Williams here.
HD132: Sara McGee vs. Mike Schofield
Sara McGee grew up in Katy, raised two kids as a single mom, and spent four decades in this district before deciding to run the day her Republican representative called her a liar about the real harms of Texas’ abortion bans. She’s run a small-dollar, ground-game campaign against Mike Schofield, a career insider who helped write the voter ID playbook and has voted against public school funding at every opportunity.
HD132 is diverse. 59% people of color, with significant Hispanic, Black, and Asian populations, and the kitchen-table issues here, housing costs, property taxes, and underfunded schools, are exactly what McGee runs on. This is a wave-seat, not a likely-seat. But a wave will happen this year. Learn more about Sara McGee here.
There are other House seats in Harris County with Democrats running, which shouldn’t be counted out. I won’t call those seats impossible, but I will call them longer shots. Those include HD126, HD128, HD129, HD130, and HD150.
However, we need to flip 14 seats to flip the Texas House. I would be looking at those four, particularly as part of those 14. Four races. Four candidates. Abbott wants to play offense in Harris County. So do we.
What it’s actually going to take.
A favorable political environment, which we will have this year, is not a victory alone. It’s an opportunity. And opportunities in Texas have long been squandered by underinvestment, poor coordination, and the assumption that a good year will do the organizing for you.
Here’s what actually moves the number in Harris County.
Turnout. Everything else is noise. Harris County has 2.6 million registered voters. The difference between a good Democratic night and a great one is activation. The people who need to vote in November already largely agree with us. They just need a reason to show up, a door knocked, a ride to the polls, or a neighbor who asked. That’s the literal mechanism by which Harris County goes from 600,000 Democratic votes to 850,000.
The precinct chair infrastructure is the backbone. Harris County has roughly 1,100 election precincts. As of earlier this year, Democrats had just over 550 precinct chairs filled. That means nearly half the county’s precincts have no one whose job it is to talk to their neighbors before November. The new Harris County Democratic Party Chair, Traci Gibson, ran on increasing the number of precinct chairs and has been working hard to make that happen.
Abbott’s campaign has already announced it will have field directors in all 24 Texas House districts in the county. They are going to knock on doors in precincts where Democrats have no one home. That cannot stand. If you live in Harris County and your precinct doesn’t have a chair, that job is yours.
The Hispanic vote is the variable that changes everything across the county. The 2024 rightward shift among Hispanic voters was real and temporary. Trump’s second term has done the persuasion work that no campaign ad could. Polling shows Hispanic voters swinging back hard to the left. In a majority-minority county where Latino residents make up the largest demographic group, that swing doesn’t just help the top of the ticket. It ripples down through every competitive House race on the ballot.
The top of the ticket matters more than people think. Gina Hinojosa and James Talarico are driving turnout in Harris County. Every door knocked for Hinojosa is a door knocked for Tyler Smith in HD138. Every phone bank shift for Talarico helps Josh Wallenstein in HD133. The races are connected. The infrastructure is shared. A rising tide in Harris County lifts every boat on the ballot.
The 2018 model showed us what’s possible when all of it comes together, the candidates, the infrastructure, the environment, and the turnout. We came within a handful of points of making history. The environment in 2026 is better. The candidates are strong. The infrastructure is more developed than it’s ever been.
The only question left is whether we show up.
Greg Abbott is about to spend eight figures trying to hold back a tide that has been rising for a decade.
He knows what the numbers say. That’s why he’s scared. That’s why he launched his campaign in Harris County.
But money doesn’t knock on doors. Money doesn’t sit in a church pew in Sunnyside and ask a neighbor if they’ve made their voting plan. Money doesn’t show up in a union hall in Deer Park and make the case for why this cycle is different. People do that.
Harris County has 2.7 million registered voters. Nearly one in five Texas Democrats lives here. The candidates are strong. The environment is the best it’s been since 2018. The infrastructure is being built right now, precinct by precinct.
What it needs is you.
If you live in Harris County, find out if your precinct has a chair. If it doesn’t, that’s your job now. If it does, volunteer for one of the many Democratic candidates on the ballot. Knock on ten doors. Make ten calls. Talk to your neighbors.
Texas flips because neighbors talk to neighbors until the people writing the laws finally look like the people living under them.
Abbott picked the wrong county. Make sure he knows it.

Harris County Democratic Party leadership is based on caucusing by Congressional District. Thanks to the Donald Trump ordered mid decade redistricting, our leadership is in flux — so many folks who have applied to be precinct chairs are waiting to be appointed until after new leaders are elected by the current precinct chairs in the district caucuses at the County Executive Committee meeting on June 16 , 2026 at Wheeler Avenue Baptist Church
