Final answer:
The right to vote is not recognized as a fundamental right by the Supreme Court in the same way as free speech, privacy, and international travel, which are protected explicitly or through interpretation of the Constitution.
Step-by-step explanation:
The question pertains to which right has not been recognized as a fundamental right by the Supreme Court. Of the options provided, the right to vote, while critically important in democratic societies, is not identified as a fundamental right in the same way that rights such as the right of free speech and assembly, the right of privacy, and the right to international travel are. These latter rights are acknowledged either through explicit constitutional protections or through Supreme Court jurisprudence that interprets the Constitution to include certain unenumerated fundamental rights. For instance, privacy rights have been interpreted from the Bill of Rights, although they are not explicitly mentioned. Similarly, freedom of movement, including international travel, has often been recognized as part of the liberty interest protected by due process guarantees. However, the right to vote, while protected and regulated through various amendments and laws, is not considered a 'fundamental' right in the same constitutional sense.
