Self interest is the prime motivator for Trump himself, so it is only natural that it be likewise with the cult of personality at large. That the whole Clowdstrike/Biden thing is not only a rank conspiracy theory, but one originated and abetted by the Russians, should be all you need to know, as it is embraced by much of the mainstream GOP.

Literally everything on the right is viewed thru this warped political prism, now even our national security, and system of checks and balances.

To illustrate how the dynamics of division have changed in the era of Trump, the things that separated right and left traditionally were issues based. Now the separation is over the definition of our experiment in self government and a re-definition of the world order that has managed to keep the peace (generally speaking) in the nuclear age.
