James Madison has been dead for a while. The supreme court has so far failed to check Trump's power and congress and the senate are in his pocket. If there ever was a time that those institutions should have acted in the interest of the nation rather than in the interest of the parties then a while ago would have been fine. Now it is late, if not too late. For all that its worth Madison's writings are irrelevant, what matters is acts and there are very few of those.
