I could just as easily say that without the 17th amendment there wouldn't have been a depression, No Social Security, no prohibition, no rise of organized crime, no NFA, No ATF, No FBI, No rise of the welfare state, and the end result would have been the utter destruction of the Democrat party. Do I really think that all would have happened? Probably not, no...but at least it's somewhat plausible, unlike suggesting that if a law hadn't been passed in 1913 then a guy in 1972 might not have been appointed.
It's absurd to suggest that if the 17th amendment hadn't passed then absolutely everything that followed would be exactly the same, leading to the exact same political compositions of states legislatures and the exact same people running for office.
You’re a very silly person. It is pointless to continue this discussion if you believe that the Democrat legislature in North Carolina would have elected Jesse Helms to the Senate five times.
