'Two of our leading deliberative democrats ask what deliberative democracy can do to halt democratic erosion. Confronting the hard realities of democrat decline, Bächtiger and Dryzek sketch out how citizen centered communicative practices can help turn back the tide of that decline. Realistic and solution centered, this is a much-needed update to the deliberative democracy paradigm.' Simone Chambers, Professor and Chair of Political Science, University of California Irvine
