Tam on the 17th Amendment.
All you ever needed to know about that particular example of cranial flatulence.
Honestly, given the fact that the 16th (income tax) and 17th (popular election of Senators) Amendments passed in 1913 (both inarguably due to “progressive” influence) followed by the 18th Amendment (Prohibition) in 1919 and the 19th Amendment (women’s suffrage) in 1920, we have the briefest period of massive (and on the part of the first three, destructive) change to the Constitution since its ratification.
Yes, I blame the Left. Yes, I think it was intentional.
