On Tuesday’s Rachel Maddow program, she described something called the Overton Window. Roughly, this is the range of acceptable ideas and ideologies to a particular time and place.
The means by which this window of reasonableness can be intentionally shifted are interesting.
This snip from the Wikipedia entry:
****Overton described a spectrum from “more free” to “less free” with regard to government intervention, oriented vertically on an axis. As the spectrum moves or expands, an idea at a given location may become more or less politically acceptable. His degrees of acceptance[6] of public ideas are roughly:
Unthinkable
Radical
Acceptable
Sensible
Popular
Policy
The Overton window is an approach to identifying which ideas define the domain of acceptability within a democratic republic’s possible governmental policies. Proponents of policies outside the window seek to persuade or educate the public in order to move and/or expand the window. Proponents of current policies, or similar ones, within the window seek to convince people that policies outside it should be deemed unacceptable.
After Overton’s death, others have examined the concept of adjusting the window by the deliberate promotion of ideas outside of it, or “outer fringe” ideas, with the intention of making less fringe ideas acceptable by comparison.[7] The “door-in-the-face” technique of persuasion is similar.****
Perhaps this is the method behind Trumps madness… Even as the other candidates (including Hillary) were lambasting Trump for his “proposals”, it was clear the problem, if anything, was he said out loud what they all believe to some extent or other anyway, but know better than to utter. So he is the straw man, the lunatic, next to which they, by comparison, appear so reasonable, as long as he is standing beside them, uttering their unutterable thoughts. He is a necessary part of the process.
