Amendment was for former slaves, not illegals - Washington Times The Beginnings of a New Constitutional Amendment: The 26th amendment (granting the right to vote for 18 year-olds) took only 3 months & 8 days to be ratified! Why? Simple! The people demanded it. That was in 1971...before computers, before e-mail, before cell phones, etc. Of the 27 amendments to the Constitution, seven (7) took 1 year or less to become the law of the land...all because of public pressure.
