If Abbott is a "Bushie," I can't find a single instance of Abbott endorsing George P. Bush during either his Land Commissioner run or his Attorney General run.
It would be very unlikely for a "Bushie" to fail to endorse the only Bush running for political office, especially in Texas.

He was an up and comer in Republican circles in Harris County (the heart of Bush country) in the 1990’s, and was appointed to the Texas Supreme Court seat by GWB.
He’s firmly in the River Oaks RINO establishment orbit, always has been.
