Final answer:
Miguel and Posner's argument indicates that ethnic identification strongly influences political perceptions and may impact democratic participation and representation, particularly for ethnic minority groups.
Step-by-step explanation:
The main argument of Miguel and Posner regarding ethnic identification suggests that belonging to an ethnic majority or minority can significantly influence one's political socialization and perceptions of government. For the ethnic majority, there may be an assumption that political decisions favoring their group are universally beneficial, which may not be the case for ethnic minorities who might experience discrimination and feel alienated from governmental policies.
The effects of this on democracy can be profound, as it may shape voting behaviors and policy priorities, potentially leading to an exclusionary political climate where the interests of ethnic minorities are sidelined.
Ethnic clustering can also play a role in how minorities may preserve their cultural identities and exert political power, especially in areas where voting districts are gerrymandered. Ethnic identification thus affects engagement with democratic processes and underscores the importance of inclusive representation to ensure a democracy that reflects its diverse populace.
