Answer:
False.
Step-by-step explanation:
Amendment Twenty-sixth to the Constitution of the United States prevents the states and the national government from exercising age as a rationale for withholding the right to vote to the residents of the United States. This Amendment prevented the governments to deny voting rights to people who were of age 18. On 23rd March 1971, U.S. Congress proposed this amendment and it got ratified on 1st July 1971. Accordingly, there is nothing informal about this amendment.
