No. Because I may be wrong, and I have been wrong.
Others are needed. As long as they are honest and not the current showboating clowns that call themselves the GOP.
We need honesty. That is how a democracy functions. The whole, “We are in this together.” thing and honest discourse.
No one person or ideology can achieve this, because they are blind to the truth. Look what ideology got us with respect to climate change, gridlock after gridlock. It has nothing to do with an authoritarian regime, it has to do with a rampant amount of dishonesty.
The issue with any single regime is that it requires one version of thing, over time even if that thing becomes untrue, which most things do. Every single authoritarian regime suffers from a need to stay in power regardless of the ground truths. That is why massive centralisation of power usually fails in the face of ground realities.
