Final answer:
The success of an interest group does not heavily depend on being supported by most Americans. Access to policymakers, organization, and financial resources are also important factors.

Other factors such as having access to policymakers in the Congress, being well organized, and having financial resources to attract the policymakers to pay attention to them also play crucial roles in determining an interest group's effectiveness.
