Trump-Backed Paxton Wins Texas Senate Primary Runoff
At 9:01pm it was confirmed that Ken Paxton – a hardliner endorsed by former US president Donald Trump – had defeated incumbent John Cornyn in the Texas Republican primary runoff for the US Senate seat. By 9:02pm, Trump began celebrating the victory on social media.
“I will do some nice, big, beautiful rallies for Ken,”the president wrote the following morning.
“Texas, this will be FUN!”
Paxton’s Democratic opponent wasted no time either. At 9:03pm, the Democrat reached out to Cornyn’s supporters, stating,
“You have a place in our campaign.”
Paxton’s Victory Highlights Trump’s Enduring Influence
Paxton’s decisive win – marking the largest primary defeat of an incumbent US senator in nearly fifty years – underscores the remarkable loyalty Trump continues to command among his base. However, Democrats remain hopeful that Paxton’s extreme positions and history of scandals will alienate some Cornyn voters and draw them to the Democratic side.
Paxton’s nomination has invigorated Democratic optimism about the possibility of winning statewide office in Texas for the first time in over three decades. This optimism is fueled by support from traditional Republicans and Latino voters who have recently shifted away from the GOP.
Fundraising Surge and Changing Political Landscape
These hopes were further reinforced by a significant fundraising boost reported last night. After already raising the largest-ever sum for a US Senate candidate in the first quarter of an election year during the first three months of 2026, Talarico’s campaign announced it had raised $600,000 within two hours following Paxton’s confirmed victory on Tuesday.
The Cook Political Report responded by adjusting its rating for the Texas Senate seat from “Likely Republican” to “Lean Republican.”
“Though polling shows the general election close or even tied, we don’t give Talarico an even chance just yet,”said Jessica Taylor, the Cook Political Report’s House and governors editor,
“though the contest could eventually shift into the Toss Up category.”
Concerns Over Paxton’s Appeal to Wider Electorate
While Paxton secured the Republican primary runoff with approximately 64% of the vote compared to Cornyn’s 36%, Democrats express confidence that the broader electorate will respond differently to a hardline MAGA candidate.
Beto O’Rourke, former Democratic congressman who narrowly lost to Senator Ted Cruz in 2018, commented to the Associated Press that Paxton is
“too extreme and he’s too tied to Trump”to attract independent voters.
Some establishment Republicans also worry that Trump’s strong hold on the party may jeopardize its control of the Senate, as his endorsement of more extreme candidates risks alienating crucial voters needed for electoral success.
Republican Frustration Over Trump’s Influence
Following Trump’s eleventh-hour endorsement last week, Republican senators on Capitol Hill openly expressed their frustration. John Hoeven of North Dakota remarked,
“Oh boy,”while noting his support for Cornyn. Alaska’s Lisa Murkowski described herself as
“supremely disappointed.”
Senate Majority Leader John Thune stated,
“He made his decision. That doesn’t change the way that I feel.”
The GOP’s Transformation Under Trump
After a decade shaped by Trump’s leadership, the Republican Party has become a machine centered around one individual. The traditional party figures, regardless of tenure, now require Trump’s endorsement. Across Texas and the nation, voters face the question not of whether the Republican Party has changed, but whether it has changed so significantly that they might consider switching their votes.
Implications for November and Voter Turnout
The results also offer lessons for Democrats and moderate Republicans ahead of the November elections.
Nearly 1.4 million Texans participated in Tuesday’s runoff, approximately 800,000 fewer than in the March primary. Paxton received about 886,000 votes, slightly more than he garnered in the primary, according to the Associated Press. In contrast, Cornyn’s support dropped from about 910,000 votes in the spring primary to just under 502,000 in the runoff.
In the coming months, both the Paxton and Talarico campaigns will focus heavily on voter turnout, aiming to mobilize those who abstained. The critical question remains: which party can better motivate voters to participate?
