I find the Mises Caucus at least useful in pushing to do more than simply be an affinity group for people pretending to play politics. I find partying with LP officials to be very hilarious, what a group of odd balls. But the party itself has no hope of electoral victory, which is why everyone should vote Republican in the current iteration of two-party politics from the libertarian lens.
As for the current political environment, I'd say that bureaucratic authoritarianism is at least the devil we know and can be routed around by individuals, whereas autocratic authoritarianism is at best a wildcard that stands to destroy a good chunk of the laws that have actually been restraining naked power.
