Yes, in one specific sense.
If democracy means equal political authority for every citizen, then this doctrine rejects democracy in that sense, and a critic who says so is reading it correctly rather than unfairly. What it does not reject is accountability, consent, rights, open entry, removal, or the rule of law, all of which are ordinarily counted as democratic and all of which are required here.
None of this rests on the claim that America was never a democracy. Madison distinguished a republic from a pure democracy, but that distinction does not make representative democracy foreign to American government, and the modern United States is correctly described as both a constitutional republic and a representative democracy. The slogan is a weaker claim than the one made here, and it is not made here.
The doctrine therefore rejects equal political authority while preserving equal rights in full. It judges government by the common good secured under law, with majority preference serving as one instrument of accountability.
The limits in Articles IX through XIII are essential safeguards against authoritarian rule.
Guardians bound by a constitution they cannot rewrite, judged by courts they do not control, removable for cause, facing a free press and a legal opposition, with entry open to any citizen, is not authoritarian government in any usable sense of the word.
Those limits are the doctrine, not trimming around it. Every authoritarian regime of the last century opened with a competence argument and then disposed of the limits, which is why the limits here are stated before the competence claim and not after it. Suspicion on that point is warranted until they are shown to bind.
It is revisionist toward the current order and continuous with the older one.
What it means to preserve is recognizably American: natural rights, liberty under law, opportunity unbound from birth, private enterprise, constitutional government, self-reliance, and national independence.
The honest qualification is constitutional. Voting rights are protected explicitly in the text, and one person, one vote was developed by the Supreme Court out of equal protection. Any actual implementation of unequal political authority runs directly into that, and this is a doctrine rather than a plan for next year.
Yes, and some of the compression will be fair.
In hostile hands the whole of this compresses to one sentence about clever people deserving more power. The answer to that is not tone, it is order. Rights come first in this document because they come first in the argument, and a doctrine that opens with hierarchy and arrives at rights later means the hierarchy.
