Query: Democratic Neutrino Mixing Reexamined   We reexamine the democratic neutrino mixing ansatz, in which the mass
matrices of charged leptons and Majorana neutrinos arise respectively from the
explicit breaking of S(3)_L x S(3)_R and S(3) flavor symmetries. It is shown
that a democracy term in the neutrino sector can naturally allow the ansatz to
fit the solar neutrino mixing angle \theta_sun \approx 33^\circ. We predict
\sin^2 2\theta_atm \approx 0.95 for atmospheric neutrino mixing and J \approx
1.2% for leptonic CP violation in neutrino oscillations without any
fine-tuning. Direct relations between the model parameters and experimental
observables are also discussed.
