The Constitution of 1787 and Bill of Rights had a good run. They held up well for 140 years. It wasn't until the FDR Congresses that our downhill slide began. Today's problems are not due to a faulty Constitution, but rather to a people who send progressives/Leftists/statists to Congress and the Presidency.

I think what passes for news these says has failed to highlight what is going on when both Democrats and Republicans generally agree. If they both want the judiciary to work a certain way, over time, it ends up working that way.
The reason I bring this up Publius, in this context, is I have some ideas on checks and balances and how a system that was meant to be adversarial has turned cooperative. When does checks and balances come up?
