The U.S. Constitution originally provided for state appointment of senators because, for all the fine words, few in power actually trusted the public.Actually the U.S. Constitution originally provided for the state appointment of senators because they were supposed to represent the states, not the people. Otherwise you just wouldn't need two houses. One house would be sufficient to do the business of the people.
He then blathers on making other supposed arguments against state appointment of Senators, couching everything in the typical left wing rhetoric, claiming that it is an effort to "overturn democracy", throwing modifiers like "radically conservative" in front of names, etc.
For the record, I would argue that states rights pretty much went away once the states weren't represented in the government. There is no one in Washington, D.C. who is fighting to protect the rights of states against encroaching federal power on a regular basis. And don't tell me about California and their sanctuary state efforts. Immigration is a federal matter, specifically outlined in the Constitution.
