Senate Majority Leader John Thune has publicly called on former President Donald Trump to endorse Senator John Cornyn ahead of a potentially divisive Republican primary runoff in Texas. Thune's appeal aims to unite the party and conserve resources by avoiding a drawn-out battle against Texas Attorney General Ken Paxton.
Speaking to reporters, Thune expressed his concerns about the implications of a prolonged intra-party fight. "If Trump endorses early, it saves everybody a lot of money, and … 10 weeks of a spirited campaign on our side that keeps us from spending time focusing on the Democrats,” Thune stated. He further emphasized the strategic advantage of securing Trump's support soon, noting, "If the president can weigh in it would be enormously helpful."
The urgency of Thune's request follows the primary election results, which did not result in a clear winner, leading to a runoff scheduled for May 26. Cornyn, who has served four terms, narrowly leads Paxton with most votes counted, a surprising outcome given earlier polls that had shown him trailing.
Senate Majority Whip John Barrasso also weighed in, supporting the endorsement: “I would encourage the president to endorse him,” Barrasso said, arguing that Cornyn presents the strongest candidacy for the general elections in November, where the victor will face Democrat James Talarico.
Despite the high stakes, Trump had remained non-committal about his support prior to the primary elections, leaving many Republicans, including Cornyn, in suspense. However, Thune and other Senate Republicans, encouraged by Cornyn’s better-than-expected performance in the primaries, are now renewing their efforts to secure Trump's endorsement.
Thune, who has yet to speak to Trump post-election, plans to intensify his outreach. His optimism is echoed by other allies of Cornyn who, speaking under the condition of anonymity, suggested that Tuesday's results might increase the likelihood of Trump's support.
As the political drama unfolds, the GOP faces a critical decision: align quickly behind a single candidate or risk a prolonged and potentially damaging internal conflict as the general election looms.
