"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.
2. The Congress shall have power to enforce this article by appropriate legislation."
The twenty-fourth amendment states that no tax can be charged to vote for any federal office.
This clip discusses how poll taxes are prohibited so voting is not limited to the wealthy. However, the amount of time it takes to vote serves as a pseudo poll tax. For instance, voting takes anywhere from two to six hours, depending on the location. Not many jobs are happy to allow their employees to take this much leave just to vote. This discourages many voters from voting because they do not have the time to do so.
