The writers of the Constitution were some very clever folks, and put together some very smart things, but good god the Senate is just a stupid thing.
Who on earth ever thought it would be a good idea to let one regionally (s)elected person have so much unchecked power in the federal government?
I think the Founders assumed the Senate would be home to rational adults not people like Rand Paul who shouldn’t be even allowed to govern even the smallest entities.
