One of my fondest wishes right now is that batshit RFK jr. will abandon the primaries and run as a libertarian. After a couple of crushing defeats, he could easily cite the hopelessness of running against a system that the deep state has rigged against him, and go off
on his own.
Repugs back him in the hope that he will somehow split the Democratic vote, but very few Democrats would be fooled. If he can gain any real traction it would split off the all important repug conspiracy dupe block from Trump.
It depends on how sincere, and therefore crazy, he really is. He just might be crazy enough to do it.
