“I think the Texas election in 2018 is powerful foreshadowing for what to expect across the country in 2020,” Cruz said.

Cruz maintained that he did not believe Democrats would be able to turn Texas blue in 2020, but said Republicans would need to turn their voters out.

“If we lose Texas, it’s game over,” he said. “I don’t believe Texas will turn blue, but central to that is we’re going to have to work to communicate and turn people out.”

Cornyn will also likely face an uphill climb in the state, which hasn't seen a Democrat win statewide in 25 years.

An Emerson College–Dallas Morning News survey released last month showed Cornyn with just a 37 percent job approval rating, while 31 percent said they disapproved.

So far, seven Democrats have stepped up to challenge Cornyn in 2020.
