Which amendment allows for the review of electoral processes in light of citizenship?

The 14th Amendment is pivotal in the context of citizenship and electoral processes. Ratified in 1868, it contains several clauses that address the rights and privileges of citizens, particularly emphasizing equality under the law. One of its key components is the Equal Protection Clause, which ensures that states cannot deny any person the equal protection of the laws. This provision has been central to numerous legal cases involving voting rights and electoral processes.

The 14th Amendment also includes the Due Process Clause, which guarantees that no state can deprive any person of life, liberty, or property without due process of law, further reinforcing the importance of lawful and fair electoral processes that respect the rights of citizens.

In the broader context of American democracy, this amendment has been used to challenge discriminatory practices and to affirm the principle that citizenship carries certain rights, including the right to vote. As such, it plays a crucial role in the review and protection of electoral processes in light of citizenship status, which is why it is the correct choice for this question.
