Abstract
It is shown that if the photon propagator is set equal to in the expression for the vacuum polarization, then (where is the photon wave-function renormalization constant) diverges like a single power of the logarithm of an ultraviolet cutoff in all orders of perturbation theory. The implication of this result upon the possible finiteness of ordinary quantum electrodynamics is discussed.
