It's interesting that you point out Loving v. Virginia. California's Supreme Court has long boasted pridefully of its 1948 decision in Perez v. Sharp striking down interracial bans on marriage in the state almost 20 full years before the U.S. Supreme Court did so. Today's ruling suggests that had the bans on interracial marriage been effected by constitutional amendment rather than legislatively, the California Supreme Court may well have upheld them. The dissenting opinion in today's decision even points that out.
