By definition, those on the right have the same philosophy as the Founding Generation.
Bullshit . . . not to put too fine a point on it. There had never been a (more or less) democratically elected republican government before in history. There had been and were republics, but their leadership was not democratically elected. There had been democratic (rather less than more) elected governments in the past, but they were not republics. There very nature of our government was a radical departure in governance.
There had never been an independent judiciary. Judges in the United States who are appointed rather than elected serve, essentially, quamdiu se bene geserit
--so long as they are well conducted, so long as they violate no laws. Judges in the European monarchies served at the pleasure of the monarch, or at the pleasure of the constituted government in the case of Parliament. In many historical examples, arguably most, there was not even an established judiciary, with judgment in matters public and private rendered by an aristocratic or plutocratic elite. Our judiciary was a radical departure in jurisprudence.
I can multiply those examples again and again. But the point is that we have the form of governance that we enjoy (and we do enjoy it, when we're being honest) precisely because the founders eschewed conservatism and struck out on a new path.
