Conservative politics in America, if thought of as a system, can be seen as in the grip of a dangerous and destructive positive feedback loop. Consider this fairly well sourced Wikipedia discussion of the kind of loop that could portend the end of American conservative politics as we have come to know it.
Mathematically, positive feedback is defined as a positive loop gain around a feedback loop. That is, positive feedback is in phase with the input, in the sense that it adds to make the input larger. Positive feedback tends to cause system instability. When the loop gain is positive and above 1, there will typically be exponential growth, increasing oscillations or divergences from equilibrium. System parameters will typically accelerate towards extreme values, which may damage or destroy the system, or may end with the system latched into a new stable state.It has become commonplace to observe that ex-Presidents Nixon, Reagan and groundbreaking conservative Republican Barry Goldwater, would be unwelcome among today's Republicans. Everyone paying attention has watched the Overton Window march steadily and ever rightward, particularly for the aging, White Americans who are the heart and soul of GOP conservatives. Everyone outside their bubble can see how carefully these people limit their misinformation about the nation and the World to what they see on Fox News and hear from a handful of radio yammerers and assorted godbotherers.
Within their bubble, American conservatives suffer from a success problem. Over the years, they have elected successively more conservative office holders. They have elected conservative Presidents and impeached or paralyzed Democrats. They have controlled houses of Congress, or crippled them. Whenever conservatives think they've won, they move further to the right. Even when they lose, they think it's because they aren't conservative enough. It looks like American conservatives are caught in a positive feedback loop.
Obviously, a sociopolitical system like the American conservative movement will never behave with mathematical precision or predictability. Still, the analogy seems useful and instructive. Subjectively, the rate is speeding up, at which the most rightward fringe of the GOP seems to be moving even further right. If that acceleration grows, what comes next could be " increasing oscillations or divergences from equilibrium. System parameters will typically accelerate towards extreme values, which may damage or destroy the system, or may end with the system latched into a new stable state."
One can only hope.
