Answer:
The saying "All politics is local" roughly means the local constituents tend to care about things that affect them.
Explanation:
Localism encompasses the political and social ideologies and philosophies that prioritize the local issues over national politics.
It conveys the truth that, since ancient Greece, politics is a matter of citizens, in other words, of the inhabitants of the city. Hommo politicus is, before anything else, a being who cares about the issues of everyday life, in which the affairs of his city are the most direct.
