  We use a simple Regge model to determine the energy dependence of the
analyzing power for pC scattering in the CNI region. We take the model of
Cudell et al which determines the Regge couplings and intercepts for the I=0,
non-flip Regge exchanges (Pomeron, f1 and \omega) and extend it to the
spin-flip amplitudes by allowing each of these exchanges to have independent
spin-flip factors tau_P, tau_f and tau_\omega. Using this we show that by
making measurments at two separate energies, with polarization known at one
energy, one can fix the ratios of the analyzing power at any energy. By making
an additional assumption that is reasonable, but not necessarily true, namely
tau_\omega=tau_f, we show that one can predict the energy dependence of the
analyzing power {using the existing E950 data}. We present the corresponding
predictions for beam energies of 100 GeV and 250 GeV protons on a fixed carbon
target based on a fit to the Spin 2000 data. Finally, we discuss the relation
of these results to the pp CNI analyzing power.
