Elastic and charge exchange scattering of intermediate energy protons from ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ and tritium is calculated with a microscopic, momentum space optical potential. Full spin dependences, form factors derived from realistic three-body calculations, and off-shell kinematics are included. High sensitivity is found to the removal of meson exchange currents from nuclear densities and to the choice of input NN phase shifts.
