It totally destroyed the "equality of representation" at the federal level between that of the people and that of the states. This destruction removed the safeguard of the states interest in defense of the people's interest. They went hand in hand as a double protection against federal over reach. The 17th destroyed one hand and smashed the other into crippled use such that today, though we have the right to vote, we have no representation.
On this post, the premise was that a state that did not ratify the 17th amendment was denied its equal suffrage. I said that the premise was not supportable because the number of votes per state delegation did not change.
See a later post of mine on this point for more clarification.
