No he is not. He is warning against what happens (and has happened) when the aforementioned “massive fraud” is not halted. One cannot say that the administration installed by said fraud is not “allow(ing) for the termination of all rules, regulations and articles, even those found in the Constitution”—the only check on same so far has been the stilted efforts of the Supreme Court.
The “rules in the Constitution as they pertain to elections” were summarily ignored between November 2020 and January 2021. It is the Uniparty that terminated them; nowhere in what Trump said does he call for doing to them what the Uniparty did to them. Please re-read, and reinsert his mention of the Founding Fathers in context.
But that is not the only take that can be gleaned from what he wrote. He needs to clarify just what he meant.
