He and others will be flying plenty by the end of 2025, which is the most optimistic timeline for Artemis 3. That's time for a lot of 6 month rotations on the ISS. Arty 3 may carry one astronaut from the new class and one "old" astronaut.

Agreed, but he checks a lot of boxes and probably has some political "qualifications" in his favor. Realpolitik wise:

• Vet with actual combat experience
• Minority
• Legit rags to "riches" story
• Solid speaker
• Not unattractive
• Young enough to do a couple terms in lower offices and still be seen as a "youthful" candidate in later runs for bigger positions (reasonable to assume a Seal/MD/Astronaut will keep his physical/mental health well above average for at least a few decades)

If he walks on the moon, that adds a helluva feather in an already impressive cap for a political candidate. I have no idea if he has any desire to pursue that path at some point, but hard to imagine he's not on the political machine's radar as someone to push. And ultimately NASA's astronaut selection is leaned on for political purposes.

Impossible, hes working on becoming the first space lawyer
