Mike Gibson, Republican Party chairman for Fort Bend County, outside Cruz’s hometown of Houston, said he thought Cruz’s convention speech was a mistake.

“I heard frustration,” Gibson said. “But then I also heard people that were very supportive of him because he was sticking by his principles. The Republican Party has been very, very good at throwing themselves on the sword, literally, over principles.”

Norma Brady Jeter, a vice president for the Texas Tea Party Republican Women, said opinions among grass-roots conservatives about Cruz’s Trump shun and subsequent change of heart remain “very much a mixed bag,” but she doesn’t see Trump supporters exacting revenge in 2018.

“We worked too hard to get him there,” she said of Cruz in the Senate. “A man like him doesn’t come along that often.”
