[Big difference between Trump and Corey, and Cruz and his NH rep nobody cares about.]
Cruz had better care about O’Brien, if he’s gonna run in 2024, and needs O’Brien’s skills and contacts. Politicians pay attention to stuff like this. As someone who doesn’t have Trump’s huge personal stash, Cruz has to make it clear to people who help him that he will return the favor. It’s not transferable - he’s not gonna endorse Lewandowski, Jared Kushner or Ivanka just because Trump endorsed him.
