Akhil Reed Amar closes his Yale course on the written Constitution with the amendments of the 1960s, read through the course's recurring themes of representation, voting, and national security. He traces how Cold War propaganda about a disenfranchised, segregated Washington D.C. fed into the Twenty-Third Amendment, and connects the same party competition for Black voters to Alaska and Hawaii statehood. He covers the Twenty-Fourth Amendment's ban on poll taxes, the Twenty-Fifth Amendment's response to presidential succession questions sharpened by the Kennedy assassination, and the Twenty-Sixth Amendment's extension of the vote to eighteen-year-olds amid Vietnam-era arguments linking military service to suffrage. The lecture ends by naming a hypothetical Twenty-Eighth Amendment and closing on the 1963 March on Washington. Chapters mark each amendment and historical turn for easy reference.
