Sanford Levinson calls the U.S. Constitution "Imbecilic" and bemoans all of the things contained therein which make governing harder.
He complains about the Electoral College, because it means the largest states get ignored. Right, because with a popular vote the entire middle of the country would be ignored, and national elections would be decided by California and a handful of moronic liberals in the Northeast.
Separation of powers and checks and balances create gridlock and make it hard for government to produce results. This is a feature not a bug. Hell, nearly everything he brings up in his piece is a feature of our Constitution, not a bug.
