Or is it that
they no longer believe in America as the Founders envisioned her?
The answer [to why the majority of Republican primary voters are no longer conservatives] lies in America's biggest -- and scariest -- problem: Most Americans no longer know what America stands for. For them, America has become just another country, a place located between Canada and Mexico.
But America was founded to be an idea, not another country. As former Prime Minister Margaret Thatcher put it: "Europe was created by history. America was created by philosophy."
If it is just that they no longer know, then principles-based movements like the ones we've been seeing might fix the problem. The problem is a problem of education. Teach people what the principles were, and why they worked, and why losing them is related to grave tragedies. Then, they will be able to apply the principles themselves and we'll see a political shift toward proper political values.
But what if -- as I have come to suspect -- the problem isn't that they don't
know but that they don't
care? I suspect they've all heard of the Declaration of Independence and the Constitution. What they want is a Federal government that will solve their problems. That implies a Federal government with all kinds of powers to 'do stuff' that is completely untethered from the Constitution.
The idea of restoring the 10th Amendment, which I think is the only way for an America that has become so morally diverse to survive, that's not important if what you want is a Federal government that will solve whatever problems you have.
Trump voters aren't conservatives because they are progressives. Oh, they're not aesthetically aligned with the progressives who want transgender bathrooms and racial diversity. They're aesthetically quite opposed to all that. But that is a difference about what constitutes a beautiful America. On the question of whether or not the government should have whatever powers it needs to make America beautiful, they're completely on the left.
