Musgraves, a Lone Star State native, was performing in central Texas during the second weekend of the Austin City Limits Music Festival.

The songstress invited O’Rourke onstage during her set.

“Honestly, I could use a drink,” she said into the mic, facing the crowd. “Is there any beer or anything out there?”

At that, O’Rourke appeared to hand the country crooner a beer. She sipped the beverage while the crowd loudly cheered.

“That really hit the spot,” Musgraves continued. The crowd’s applause then transitioned into a booming “Beto!” chant.

Abhi Rahman, a former O’Rourke spokesperson and a Texas Democratic strategist, told Newsweek about the role Texas women will play in the upcoming election.

“Kacey Musgraves is the most popular musician in Texas and quite possibly the country,” Rahman wrote. “Her support is part of a broad coalition of Texans supporting Beto and further proof that women of all ages will decide the governor’s race in Texas.”

O’Rourke will face off with Republican Governor Greg Abbott during the November 8 election.

Other Texas-born celebrities have similarly condemned the incumbent. Boyhood and Dazed and Confused director Richard Linklater recently teamed up with a group of Texas women called Mothers Against Greg Abbott for a series of attack ads.

Last week, the group of anti-Abbott moms released another viral video, featuring a pregnant child, that blasted the governor’s anti-abortion stance.

Abbott’s popularity has been pockmarked in recent months. Many critics on both sides of the aisle are unhappy with his handling of events like the COVID-19 pandemic and the February 2021 winter storm.

A September poll, however, showed O’Rourke trailing behind his opponent by 5 percentage points.

O’Rourke’s campaign has pushed to mobilize voters following the Texas Legislature’s strict abortion ban. The candidate’s website argues that the governor’s “attacks on reproductive freedom” are stripping the state’s women of access to essential care.

The Democrat also notes that the state ranks last in the country for maternal and prenatal health care access, “which helps to explain how our state—the ninth largest economy on planet earth—has one of the highest maternal mortality rates in the developed world.

“This ends when I’m governor,” O’Rourke campaign website continues. “I will trust Texas women to make their own health care decisions.”

Texas Republicans’ staunch anti-abortion stance may have alienated more moderate conservatives. This past spring, polling showed that 78 percent of the state’s voters support access to the procedure in some form.

Musgraves has been outspoken about her political views before.

During the first weekend of this year’s ACL Music Fest, the six-time Grammy winner trolled a Texas Republican who competed against O’Rourke in the 2018 senator’s race.

“Cause everyone knows someone who kills the buzz every time they open their mouth—Ted Cruz,” Musgraves sang in a slightly adjusted version of her hit single “High Horse.”

After that, she added: “I said what I said.”

Newsweek reached out to a representative of Musgraves for comment.
