Abstract
A fit to the existing pion electroproduction data is presented. This work builds upon our previous analyses of pion photoproduction and elastic pion-nucleon scattering over the Delta resonance region. We comment on the extraction of E_1+ ^3/2 / M_1+ ^3/2 (E2/M1) and S_1+ ^3/2 / M_1+ ^3/2 (S2/M1) ratios, and note that the E2/M1 ratio approaches, and possibly crosses, zero below a Q2 of 5 (GeV/c}^2.
