In Texas, voters will notice a lack of public appearances from Republican U.S. Senate candidates on Monday, unless they turn to screens. Neither Senator John Cornyn nor state Attorney General Ken Paxton have scheduled public campaign events on the final day of their lengthy quest for the GOP nomination. Their battle, spanning over a year, remains fierce and continues through hefty advertising, with spending over $109 million, largely from Cornyn’s side.

Cornyn plans to host his annual event in San Antonio to honor high school graduates attending the nation’s service academies. This is classified as a non-campaign event. His last public campaign appearance was in Corpus Christi on Friday, preceding Tuesday’s voting. Paxton’s final events took place on Thursday in the Austin area and San Antonio. He now relies on his campaign and a super PAC to promote his main message: President Donald Trump’s endorsement on May 19. This endorsement accompanied a dismissal of Cornyn, who maintains a tense public relationship with Trump, and was announced during the second day of early voting, which concluded Friday.

Although the candidates remained silent over the weekend, Trump reinforced his support for Paxton on Sunday, while criticizing Cornyn for not showing enough loyalty. On social media, Trump praised Paxton for his loyalty and labeled Cornyn as disloyal. Trump’s rebuke of Cornyn follows his criticism of Louisiana Senator Bill Cassidy, who lost in the May 15 GOP Senate primary. Encouraged by Trump’s calls for action, Republican voters in Indiana and Kentucky have selected GOP primary challengers over incumbent GOP officeholders who opposed Trump’s agenda.

The contest aims to engage a small fraction of Texas’ 18.7 million voters. Campaigns and their supporting groups are flooding Texans with advertisements, particularly from Cornyn’s camp. Wayne Hamilton, a former executive director of the Texas Republican Party, described the race as a “slugfest” with campaigns and third-party groups clashing intensely.

Over the past year, Cornyn’s campaign and supporting super PACs have outspent pro-Paxton groups significantly, with nearly a nine-to-one ratio. However, the spending gap has narrowed as the runoff approaches. In the campaign’s final week, pro-Cornyn ad spending was less than double that of Paxton’s group. Cornyn’s network continued running ads attacking Paxton regarding ethical and personal issues that have persisted with minimal impact throughout the campaign. Cornyn’s team also revived an ad highlighting his Senate votes in favor of Trump’s priorities. Meanwhile, Paxton’s campaign and supporting groups shifted midweek to focus on Trump’s endorsement in their ads. Paxton’s primary super PAC, Lone Star Liberty Fund, launched a new ad over the weekend questioning state Rep. James Talarico, the Texas Democratic Senate nominee.
