James Freeman had an interesting op-ed on this subject. At the end of his piece, he quoted Michael Baharaeen, who blogs at the Liberal Patriot [emphasis in the quote]:

One such risk [political…of focusing on identity politics] is coming to believe that the shared characteristic that binds a group of people together is the most important factor informing that group’s voting habits… conceiving of any group in monolithic terms risks missing meaningful differences within it. Even terms like “Latino” have limited utility, as they lump the very different life experiences of people with ancestry in, say, Mexico, Cuba, and Colombia into one broad category….

Indeed. It might be more useful, instead, to focus on the differing positions, perspectives, ideas themselves without any regard for who, or which group, has them. Maybe Party would be better served, be more attuned to what makes us all Americans, to treat us all as the individual Americans that we are, rather than as this or that collected subset of us and then pretend to care about each group.
