He will be the future of the MAGA movement once Trumps loses. He will be much harder to win against. I think you missed something though- Waltz came off as being much more conservative than I expected BUT a refreshing conservative one with a heart and desire to take this country to better places. IMHO Waltz showed the "undecided" that Harris is more conservative than they thought- a win.
I also think Vance really outshine Trump which may not be a good thing for him since people keep trying to shoot him, in his own party.
I wonder if Peter TheiL is making a move for 2028.
