Then build either an electoral majority or a SCOTUS majority. Those are the only two ways the Founders would have you do it.
No, that's where your majoritarian, mob-rule mentality is obscuring reason. The framers of the Constitution deliberately and specifically created a government that countered pure democratic rule.
As I alluded to earlier, there can come a point where a significant majority dismisses the value of protecting minorities. They can amend the Constitution legitimately to do away with limited government protection, or they can elect leaders who will pack the Court with unscrupulous judges who will do it for them. If and when that happens (and though it hasn't quite yet, we are on the cusp), the plans of the Founders are defunct.
You seem to be of the opinion that we've already conceded to the majoritarian premise. If you believe that's true, then simply lay claim to the "dictatorship of the proletariat" and move on. No need to sully the names of historical figures with modern bungling.
