It does seem like all the hoohah about how great the US Constitution is, or the genuis of the US founders may well have just been some good marketing mixed with a reliable dash of American Exceptionalism.
The problem with any constitution is that it's not self-enforcing. Any system can be subverted and corrupted. It's the corruption that's the problem, not that the Constitution (like any set of laws) is not perfect.
A crazy, washed-up former reality TV host running for a new term as president while in exile on the moon sounds like the plot of a fun sci-fi political thriller, but not a reality I want to live in.
