Twenty-Fourth Amendment (1964)

Section 1. The right of citizens of the United States to vote in any primary or other election for President or Vice President for electors for President or Vice President, or for Senator or Representative in Congress, shall not be denied or abridged by the United States or any State by reason of failure to pay any poll tax or other tax.

Section 2. The Congress shall have power to enforce this article by appropriate legislation.

The Twenty-Fourth Amendment got rid of the poll tax. It also gave Congress the authority to enforce the amendment through legislation. 

This cartoon illustrates the terribly constraining effects of the poll tax on citizens' ability to vote for change. http://bvapush.pbworks.com/w/page/4313391/Amendment-24 

This video recounts the history behind the ratification of the 24th Amendment. This video highlights the voting disparities between the wealthy and the poor. I enjoyed the accompanying music very much.
