Abbott, who has been governor of Texas for three terms, previously spent more than a decade on the bench in Texas’ judicial system. In 1995, then-Gov. Bush appointed Abbott to the Texas Supreme Court. He was then re-elected twice in the late ’90s.

He later served as the state’s attorney general for over a decade beginning in 20022, before running for Texas governor in 2014. He won the seat that year by over 20 points against state Sen. Wendy Davis.

“​​If Greg Abbott, the Governor of Texas, hadn’t become a RINO in the last six months of his Political Life, he wouldn’t have lost,” President Donald Trump wrote in a post on Truth Social following news of Abbott’s loss. “He went back to his original formula, and it wasn’t pretty!”

Abbott is just one of a number of Republicans who have suffered defeats on Tuesday amid a wave of Democratic victories in long-red Texas that are sending shockwaves through the political world.
