  We study quantization of a minimally gauged massless Rarita-Schwinger field,
by both Dirac bracket and functional integral methods. The Dirac bracket
approach in covariant radiation gauge leads to an anticommutator that has a
non-singular limit as gauge fields approach zero, is manifestly positive
semidefinite, and is Lorentz invariant. The constraints also have the form
needed to apply the Faddeev-Popov method for deriving a functional integral,
using the same constrained Hamiltonian and inverse constraint matrix that
appear in the Dirac bracket approach.
