Answer:
The statement is true. In countries with federalism, subnational governments are always represented in the upper house of the national legislature, enabling regional interests to influence national lawmaking.
Explanation:
Federalism is a form of state in which sovereignty is shared between the central or national or federal level and the states. Â This sharing of sovereignty is shown within Congress, in which there are two chambers, one based in population and other in which each subnational entity is represented equally.
