When I was young and in school, I learned about the 3 branches of our government. As I understood it, the 3 shared power and each was different but served as a check on each other. Seemed to me, it was a great idea. And I still think it should work than way.
But it doesn’t seem that way now. Congress seems to be more of a rubber stamp for what the President wants. They might argue a bit but in the end they always seem to agree with the President. The Supreme Court seems to do about the same.
But when I was young was over 50 years ago. But I still think the branches of government sharing power is a good idea. I still can’t get used to the idea of a President with unlimited power (or a king or a dictator).
