There is another way: give that power to everyone in academia by turning all those adjunct positions into tenure track positions. That's the way it used to work, and the only way it is can work. You talk about Conservatives being easily overpowered, but that's only within academia. Without tenure, conservative figures outside of academia (politicians like Ron Desantis) could get any professor fired at will, just because they disagree with their ideas. Progressive POCs wouldn't have a chance in a system like that.
