Now that is truly an interesting idea! I’ve actually pondered on that!
I think...........that it would have the effect of seriously restraining Federal Central Gov’t authority over the States.
Found at Wikipedia: “Critics of the Seventeenth Amendment claim that by altering the way senators are elected, the states lost any representation they had in the federal government and that this led to the gradual “slide into ignominy” of state legislatures,[2] as well as an overextension of federal power and the rise of special interest groups to fill the power vacuum previously occupied by state legislatures. In addition, concerns have been raised about the power of governors to appoint temporary replacements to fill vacant senate seats, both in terms of how this provision should be interpreted and whether it should be permitted at all. Accordingly, noted public figures have expressed a desire to reform or even repeal the Seventeenth Amendment.”
