Trumpism swept away the old guard conservatives for the most part, and they would still call themselves "constitutional," just with a radically different interpretation of the constitution. I think the techno-feudalists are trying to parasitize the Trump movement the way the Trumpists themselves did the conservative movement through Musk, DOGE and Palantir.
"Constitutional" always meant "my specific interpretation of the Constitution". That's part of what made it so easy for the old guards to be swept out and replaced by people with an even more self-serving interpretation.
