I suggest you are not seeing that which does exist.
I cannot see anything on there that suggests Trump intends to do away with the Constitution, unless you are suggesting that he’s also into large-scale electoral fraud. Nowhere is it stated that ignoring the Constitution is the remedy to its subversion by fraud.
When he brings the Founding Fathers into it, it ought to clarify that he is quite against subverting the Constitution and is pointing out that the Uniparty is certainly doing it, evidence for which abounds plentifully.
