Same problem as communism, no? "We'll need a preemptive stage where we have a few guys, "the party", calling all the shots for the entire population, but once we get things straightened out we'll return the power to the worker, pinky swear"
Unless you go to explicitly authoritatian circles most communists (atleast the western ones I interact with) are explicitly against so-called Vanguard parties. A hypothetical communist revolution can be a slow transition without needing an authoritarian party to rule foe the course of it. Autocrats don't really want to give up their power.
Another 30 years of wage stagnation, rising income inequality, and shared prosperity running on empty and the average Joe will be willing to give much shadier characters than "the party" a try.
