Each individual accomplishes it by not compromising or withholding what they have recognized to be true.
That is the nature of American conservatism: Self-evident Truth rendered in the hearts of individuals for whom Almighty God hath created the mind FRee; Individuals protected by the Laws of this Republic against the tyranny of the majority.
So, I will not vote for someone whose history I recognize as self-evidently being one of persistent, politically expedient, moral compromise.
That’s how I’ll accomplish it for myself between now and November. YMMV.
