Guardian columnist Sidney Blumenthal argued on Saturday that Sen. John Cornyn’s recent primary defeat to Texas Attorney General Ken Paxton marks a terminal shift in the Republican Party. Blumenthal said the transformation has shifted the organization from a policy-driven institution to a personality-focused movement, arguing that Cornyn’s expenditure of $92 million during the Senate primary—the greatest amount ever spent by a candidate in that race—failed to prevent his loss to Paxton.
Paxton secured the nomination with former President Donald Trump’s endorsement, Blumenthal reported, despite facing a list of legal allegations including bribery, abuse of office, and felony securities fraud, as well as a previous impeachment by the Republican-controlled Texas House. Blumenthal characterized Cornyn’s rejection not merely as a personal loss but as the ongoing shattering of the Republican foundation built by Ronald Reagan, the Bush family, and Senate Minority Leader Mitch McConnell.
The column traced Cornyn’s political origins to the early 1980s, when he first met political consultant Karl Rove. Blumenthal reported that Rove enlisted Cornyn through a “tort reform” movement, helped slot him as a state district judge in 1984, and recruited him for a Texas Supreme Court run in 1990. Blumenthal wrote that Rove subsequently helped Cornyn win the attorney general race in 1998, which set up his U.S. Senate bid in 2002 to fill the seat vacated by Phil Gramm.
Blumenthal wrote that Cornyn rode the Reagan wave to be raised as a “factotum” of the Bush operation, serving as a conduit for oil and gas industry funds that fueled McConnell’s political operations. The columnist reported that those funds helped destroy campaign finance reform, finance Republican candidates, and secure the conservative majority on the Supreme Court.
During his tenure as attorney general, Cornyn co-founded the Republican Attorneys General Association, according to Blumenthal’s reporting. After Republicans lost the Senate majority in 2006, Blumenthal noted that Cornyn aligned with McConnell, heading the National Republican Senatorial Committee in 2009 where he raised over $100 million to help retake the Senate in 2010. McConnell subsequently named Cornyn the Senate whip in 2012.
Blumenthal argued that Cornyn preserved the campaign finance system following the Supreme Court’s 2010 Citizens United decision. The columnist reported that Cornyn battled the Democrats’ Disclose Act and attached riders to appropriations bills to restrict the Securities and Exchange Commission from making campaign donor disclosure rules. Blumenthal stated that Cornyn raised at least $415 million over the years for Republican PACs and linked the senator’s operations to networks associated with Leonard Leo and the Federalist Society.
Blumenthal highlighted the structural links between Cornyn and the networks operated by Leonard Leo, chair of the Federalist Society. The columnist reported that Cornyn’s former chief of staff, Monica Popp, headed a dark money group called the Conservative Majority Project, which distributed $1.5 million in 2024 to Right Vote, a non-profit funded through Leo’s Concord Fund.
The analysis addressed the fallout from the Jan. 6, 2021, Capitol assault, noting that McConnell denounced Trump and certified the 2020 election. Blumenthal reported that Cornyn followed McConnell’s lead in certifying the election but voted to acquit Trump during the subsequent impeachment. Blumenthal wrote that Trump viewed Cornyn’s actions as “VERY disloyal” and targeted him alongside McConnell.
During his re-election bid, Cornyn attempted to appeal to Trump’s base, Blumenthal detailed. The column reported that Cornyn posted a picture of himself reading “The Art of the Deal,” posed in front of a Trump-themed restaurant in Houston, and introduced legislation to rename Interstate 47 “Trump Interstate.” Despite these efforts, Trump endorsed Paxton, whom he called a “true MAGA Warrior.”
Blumenthal concluded that Cornyn’s traditional methods of party advancement were ineffective against a personality-driven movement. The column noted that the National Republican Senatorial Committee immediately began scrubbing Cornyn’s TV advertisements after the primary, an action Blumenthal characterized as an attempt to erase the remnants of the old party structure.
