The March 3 primary elections in Texas saw unusually high turnout in Harris County, signaling strong voter engagement and underscoring the continued influence of Black voters in shaping Houston’s political landscape.
According to Harris County Clerk Teneshia Hudspeth, the county saw a “record-breaking” turnout in the non-presidential primary election cycle, with more than 565,000 voters participating. Early voting saw more than 346,000 voters cast ballots in person or by mail, with more than 200,000 ballots cast on Election Day.
Out of these, almost 366,000 ballots were cast in the Democratic Party, with a little under 200,000 voters in the Republican Party.
“Early voting was definitely the record-breaking trend this election cycle,” Hudspeth told the Defender. “This election cycle, we did not get the parties to agree to a joint primary. That brings a whole other aspect for logistical purposes for our operations behind the scenes…we probably doubled the work in this election cycle than we typically see in a spring primary.”
The high turnout, analysts say, reflects growing political engagement as voters respond to national political tensions and local issues that directly affect communities across Houston.
Beyond the raw numbers, the results underscored the continuing power of the Black vote in key races, particularly in historically significant districts such as Texas’ 18th Congressional District.

A pivotal race in a historic district
For many political observers, the race in Congressional District 18 was among the most closely watched.
The district, which has long served as a political anchor for Houston’s Black community, saw a competitive Democratic primary that ultimately led to a May runoff, with no candidate topping 50% in the race.
Christian Menefee, currently serving TX-18 after winning the January runoffs against Amanda Edwards, led with 46%, compared to 44% for longtime Congressman Al Green. The remaining 10% of the vote was split between two other Democratic candidates, Edwards and Gretchen Brown.
Michael Adams, a professor of public affairs and director of the master of Public Affairs graduate program at TSU’s Barbra Jordan-Mickey Leland School of Public Affairs, said the district’s race reflects broader political dynamics shaping Houston and other urban areas in Texas.
“The district that probably has the most focus for Black Americans in the Houston area is the historic 18th Congressional District,” Adams said. “So Black voter turnout shaped what we saw in early voting. That was historic. It was also good to see because the districts are so heavily slanted.”
Adams noted that the election also occurred amid ongoing debates about redistricting and representation in Texas.
The influence of Black voters, he said, could also shape several down-ballot races and determine who advances to the next stage of the election cycle.
“The power of the Black vote was on full display,” Adams said.
Turnout driven by competitive races
Political scientists say competitive races and national political tensions likely contributed to the strong turnout.
Brandon Rottinghaus, a professor in the Department of Political Science at the University of Houston, said higher participation is consistent with voter behavior when elections are perceived as particularly consequential.
“Competitive races drive turnout,” Rottinghaus said. “So it definitely tracks with what we know about voter habits to see a big turnout in a year where these races have become nationalized. Many were reacting to the lackluster turnout in 2024 as a cause of many of their woes. This, for a lot of Democrats, was an opportunity to right that ship.”

was a partial referendum on
Donald Trump in his presidency.”
He added that many voters were motivated by broader political developments, including reactions to national leadership and policy debates.
“This was a partial referendum on Donald Trump in his presidency,” Rottinghaus added. “Democrats reacting to the way the Trump administration has proceeded on policy, ideology, and the rhetoric, and it definitely has had them showing up in full force.”
He also said that coalition politics played a role in determining which candidates gained traction.
“Trump will be kingmaker for the Republican Party in Texas,” he said. “The Latino vote is rising in importance. The Black vote was decisive for the Democrats, as it always is.”
Community leaders stress the importance of representation
For community leaders on the ground, elections are a direct indication of potential resources and representation, especially in historically underserved neighborhoods.
Deloyd T. Parker Jr., co-founder and executive director of the SHAPE Community Center in Houston’s Third Ward, said the outcome of elections determines whether the needs of Black communities are prioritized.
“The African-American community is already the underserved community in this city,” Parker said. “We definitely would be underserved if the person in the position did not have the community needs as a priority. It would have an impact on my community.”
Because of that, he said, voters must carefully consider the candidates who will represent them.
“We have to make sure that whoever wins is sincere, has a history or an interest in our community and the uplifting of our community,” Parker added. “What happens with this election has a lot to do with how SHAPE is affected socially, culturally, economically, politically, and spiritually.”
Elections and everyday quality of life
Experts also say elections affect daily life in ways that are not always immediately visible to voters.
Carol Lewis, an emeritus professor of transportation studies at TSU, said the policies chosen by elected officials can shape infrastructure and public services that residents depend on.
“I am 100% thrilled that turnout was as high as it was, particularly on the Democratic side,” Lewis said. “The opportunity for the electorate to make our voices heard and to get out in such a strong way in Texas, which we hadn’t seen in a while, was very encouraging.”
Lewis said transportation is one example of a policy issue often overlooked in campaigns but critical to residents’ quality of life. She said the transportation decisions affect the justice system, access to jobs, healthcare, and education.
Looking ahead to runoffs and November
Despite the high turnout in the primary, experts say voter participation could drop in the upcoming runoff elections.

Mark Jones, a professor in the Department of Political Science at Rice University, said the dynamics of runoff elections often lead to significantly lower turnout.
“What will be the challenge for both the Menefee and Green campaigns is to accurately target their voters and then ensure that their voters turn out to vote in a runoff where there won’t be the marquee race for U.S.,” Jones said, referring to statewide contests that help drive voters to the polls.
That means campaigns will need to mobilize their supporters more aggressively. Jones also said that the high turnout in the primary was partly driven by enthusiasm for statewide candidates.
“Turnout was so high…in large part due to the massive support for Jasmine Crockett within the African-American community,” Jones added. “Three-fifths of Democrat primary voters in [Congressional] District 18 are African-American, many of whom turned out to vote not because of this congressional race, but rather because of the US Senate race and their desire to support Jasmine Crockett.”
A preview of Houston’s political future
The March 3 primary elections served as an early indicator of political momentum heading into the general election and revealed the coalitions that candidates will need to build moving forward.
With more than half a million voters expected to participate in Harris County’s primary elections, the results suggest that Houston residents, particularly in Black communities, remain highly engaged in shaping the region’s political direction.
But a gap remains in young voter turnout.
“There is higher enthusiasm among Democratic primary voters as we look ahead towards November,” Jones explained. “We didn’t see a substantial number of new voters turning out to vote in the primaries. What we did see on the Democratic side was a large number of people who normally vote Democratic in November, but don’t vote in the primaries, this time around voting in the primary.”
However, Harris County remains reliably Democratic, making it difficult, though not impossible, for Republicans to win countywide races in November, Jones said.
Rottinghaus positions Harris County as a statewide battleground, saying it will be critical in determining statewide outcomes in Texas. Republicans are expected to invest heavily to gain ground there, while Democrats’ strategy could include maximizing turnout and margins in the county to have a chance at winning statewide races.
In short, Harris County is likely to be decisive in the 2026 elections.
