Final answer:
Gary Marbut is an advocate for gun rights with a skeptical view of federal authority, favoring state sovereignty. He is not directly connected to Morton Grodzins' concept of marble-cake federalism.
Step-by-step explanation:
Gary Marbut is known as an advocate for gun rights and has often expressed his views regarding states' rights and his skepticism of federal authority. While there isn't a specific record within the context of Morton Grodzins' marble-cake federalism, which describes the intermingled responsibilities and activities of federal and state governments, we can infer that Marbut likely supports a more distinct separation of powers, favoring state sovereignty. As the question seems to mistakenly intertwine Gary Marbut with concepts of federalism, it's important to clarify that Marbut's views are more closely related to the advocacy for firearms rights and less to the academic discussions on the nature of federalism.
