Stack comes along and agrees that termination of the Constitution is the appropriate thing to do in the case of fraud and that it is not such an outrageous thing to say, but says there wasn't no fraud so it doesn't matter.
Not sure how you arrived at all that. I just said your point is moot. There was no fraud so whether the constitution speaks to presidential election fraud or not is neither here nor there. As honk pointed out, there is a mechanism that is in the constitution, impeachment.
As well, there has been much debate over just such a scenario. Some legal scholars claim that Article II of the Constitution prevents holding a presidential election again whereas others point to some case law where courts may interpret the constitution differently and allow a redo. So to say "Trump is right" is just blindingly partisan and, in fact, incorrect, as it has not been determined one way or the other.
As far as Trump goes, totally to be expected. 3 years on, still claiming there was fraud without a shred of evidence and then saying we should ditch the constitution. He's just playing to the delusional idiots who still idolize him...Pillow guy, et al, and filling his coffers.
