The Wall Street Journal editorial page — always a steadfast friend of federalism — is nevertheless unconvinced by the “federalism brief” in the Defense of Marriage Act (DOMA) case. The editors write:
[L]iberals and some libertarians argue [that DOMA] is an offense to federalism. We disagree …. In the Constitution’s system of dual federal-state sovereignty, each coequal sovereign has the power to define marriage for its own sphere.
As I have explained, here and here, this is exactly right.
