Sen. Ted Cruz Rafael (Ted) Edward CruzMurkowski: Supreme Court nominee should not be taken up before election Battle lines drawn on precedent in Supreme Court fight Sunday shows - Ruth Bader Ginsburg's death dominates MORE (R) on Tuesday night released a country radio jingle attacking Democrat Beto O’Rourke shortly after the two won their respective primaries in Texas.

The song, titled “If You’re Gonna Run In Texas,” is 60 seconds and will be played across the state, Cruz said.

“If you’re gonna run in Texas, you can’t be a liberal, man. 'Cause liberal thought is not the spirit of a Lone Star man,” the song begins.

The tune goes on to attack O’Rourke for going by the name Beto instead of his given name, Robert, and for his policy views. Cruz's birth name is Rafael.

“Beto wants those open borders and wants to take our guns. Not a chance he’ll get a vote from millions of Texans,” the song goes.

The Associated Press called the U.S. Senate primary races in Texas for Cruz and O’Rourke, respectively, less than an hour after the polls closed.

O'Rourke, an El Paso resident, raised $2.3 million in the first six weeks of 2018, compared to Cruz's $800,000 over the same time period.

Cruz earlier Tuesday acknowledged the surge of energy among Democrats across the state, saying it's "absolutely" a cause for concern.
