Ken Paxton Voting Allegations Draw Focus to Texas Senate Race

In Houston, where Harris County voting fights often spill into statewide politics, a new accusation against Texas Attorney General Ken Paxton is adding another layer to the 2026 U.S. Senate race. Paxton has long promoted election fraud investigations, but his Republican primary opponent, U.S. Sen. John Cornyn, is now accusing him of breaking Texas voting law himself.

The dispute centers on Paxton's vote in the 2020 election. According to ProPublica, Cornyn's campaign says Paxton cast a ballot in Collin County while living in a home in suburban McKinney that had not yet been fully built and did not appear suitable for occupancy at the time. Paxton has denied wrongdoing and said he voted legally.

John Cornyn campaign points to Paxton's 2020 vote

ProPublica reported that Cornyn's campaign filed a complaint with the Texas attorney general's office election integrity division. The complaint argues Paxton voted from an address where he was not lawfully residing when he cast his ballot in 2020. Texas law generally requires voters to register at their residence, though legal disputes can turn on how residency is defined and whether a voter intended a property to serve as a home.

The allegation carries extra weight because Paxton has made voter fraud a signature issue during his time as attorney general. He has backed investigations, publicized prosecutions and positioned himself as one of Texas' highest-profile voices on election enforcement. Cornyn's campaign is using that record to argue Paxton should face the same scrutiny he has demanded for others.

Paxton denies any violation as Senate contest grows

Paxton told ProPublica he did nothing illegal. The report says he maintained that he voted from the address lawfully and rejected the accusation from Cornyn's camp. The complaint arrives as Paxton and Cornyn prepare for a closely watched Republican primary that could become one of the state's biggest political fights of the 2026 cycle.

The issue also lands in a state where election administration remains a major political flashpoint. Harris County, including Houston, has faced repeated legal and legislative battles over voting rules, ballot access and election oversight. That gives statewide allegations involving voting conduct added visibility here, even when the case itself is tied to North Texas.

Why the case matters beyond North Texas

No court finding or criminal charge has been reported in connection with the allegation described by ProPublica. At this stage, the matter stands as a complaint filed by Cornyn's campaign and a denial from Paxton. The report frames it as a political and legal test of how Texas applies the residency rules behind its voting laws.

That question may remain in public view as the Senate race develops and as Paxton continues his statewide role. Any formal response from the attorney general's office, election investigators or the campaigns would add the next concrete step in the case.
