We reexamine several issues related to the physics of scaling in electron scattering from nuclei. A basic model is presented in which an assumed form for the momentum distribution having both long- and short-range contributions is incorporated in the single-particle Green's function. From this one can obtain saturation of nuclear matter for an NN interaction with medium-range attraction and short-range repulsion and obtain the density-density polarization propagator and, hence, the electromagnetic response and scaling function. For the latter, the shape of the scaling function and how it approaches scaling as a function of momentum transfer are both explored.
