I think we should be at least several decades past looking at the USA as a particularly functional democratic system...
The US constitution, despite its biblical status in their culture, manages to be more of a distracting throw-word ("LOOK at how this bill helping provide healthcare OBSTRUCTS your CONSTITUTIONAL RIGHT to NOT CARE ABOUT THE POOR!" (Ok, not a great example)) than a functional constitution that limits institutional overreach.
