If Abbott was not disabled he would be a 2024 or 2028 contender; I see him as a future Republican AG.
Putting aside my partisan hack nature for a second, Abbot isn't going to let that stop him at all. Abbott could very well run in 2024.
Anyway, the entire TX-GOP list of officials are groaning in frustration at this story. TX GOP officials are all waiting for Abbott to move on so they can move up. It's probably overall the best thing that could happen to the party as Abbott is WAY popular than, say, Patrick or Paxton or George P. Bush, who would be the primary candidates for the next governor's race if Abbott were going away.
