A gauge invariant model based on $\ensuremath{\pi}$ and $\ensuremath{\rho}$ Regge trajectory exchanges provides a successful and economical description of the forward charged pion electroproduction reactions above the resonance region. Its sensitivity to the meson form factors is investigated in kinematics where the pion electromagnetic form factor will be extracted at high ${Q}^{2}$ at TJNAF. An extension to ${K}^{+}$ electroproduction is presented.
