The main idea here is how U.S. Senators are chosen. The quote points to voters directly selecting their Senators rather than having them chosen by state legislatures. That describes the change made by the amendment, which established that Senators are elected by the voters in each state, shifting power from state legislatures to the people. This reform was ratified in 1913 to curb deadlocks and reduce corruption or undue influence in how Senators were placed in office, aiming for greater accountability to the electorate. The other amendments focus on who can vote or when, not on how Senators are selected. The 15th prohibits racial discrimination in voting, the 19th extends suffrage to women, and the 26th lowers the voting age to 18. None of these address the method by which Senators are chosen, so the described idea fits best with the amendment that moved to direct popular election of Senators.
