According to our constitutional conception, modern democracy is multidimensional: it incorporates the values of faction control, minority rights protection, and informed deliberation, as well as political accountability. The impact of multilateral organizations (MLOs) on democracy is often not straightforward: it requires careful analysis of how particular MLOs interact with preexisting domestic political institutions within specific issue-areas. Thus we reject the conventional wisdom that MLOs are necessarily democracy-degrading simply because they are not directly participatory. Gartzke and Naoi's critique misstates our views on some fundamental issues. We clarify our analyses of the multidimensional nature of constitutional democracy; the relationship between democracy and multilateralism; the Madisonian distinction between interest groups that support the general interest and those that do not; and our understanding of the current state of research. We suggest possibilities for further elaborating our argument, theoretically and empirically.
