comment Kallen–Lehmann spectral representation for an arbitrary spin
@fqq : I haven't found the info about spinor propagator L-K for in the Srednicki book. Can you tell me the page?

For the description of free electron you don't need info about it's charges (leptonic, electric etc.).

comment About constraints of the first class and electrodynamics
No, it doesn't. We eliminate the second class constraints by introducing the Dirac brackets for the equation of motion, and after that can strongly set the secondary class constraints to zero. After that we can reduce the number of degrees of freedom.
