Listen, the fact is we are already a social democracy. There is no way that were going to turn back hundred years of social change in order to invent some sort of constitutional republic that we were founded on.
I understand what the founders intended. I also understand that we are so far from what the founders intended that there’s really no way to turn back without completely scraping the platform of all problems and starting from scratch. Unfortunately, that’s going to require revolution in a big way.
The problem isn’t, as you propose, that the politicians are acting in accordance with the Constitution. The problem is that they are acting outside of the Constitution.
The reason we strive to achieve constitutional government is that we dont have it now. A government constrained to only legislating within their granted powers would not breed a social democracy.
in order to invent some sort of constitutional republic
We do not need to invent a constitutional Republic; the founders invented it for us by guaranteeing to every state in the Union a Republican Form of Government.
Article 4, Section 4 - The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened), against domestic Violence.
Your representatives took an oath to uphold the guarantee of a Republican Form of Government and you have the legal as well as the moral right to demand they honor their oath.
The problem isnt, as you propose, that the politicians are acting in accordance with the Constitution.
The problem I proposed is that politicians are not acting in accordance with the Constitution hence my desire for a constitutional government.
what the founders intended
That is the point. The Constitution contains what the founders intended for us. The corrupted and corruptible have subverted what the founders intended but they did not take the step of amending the words. The words remain and you have the right to demand that the words be followed.
