The Republican Party will not be able to win elections without an enthused white base. Democrats will need to build a platform that’s even more explicit in its pursuit of racial and gender equality, while Republicans will need to design a politics even more responsive to a coalition that feels itself losing power. This dynamic is behind much of the panic about “identity politics.” When a single group dominates the political agenda, its grievances and demands are just coded as politics, and the vast majority of policy is designed in response to its concerns.
