Vector potentials and their associated fields are embodied in the left and right spin connections and their spin curvatures. Theses measure the path-dependence of the transport of spin frames, or the "vorticity of the spinfluid," produced by local sources. Electroweak interactions emerge from PT-antisymmetric u(1)xsu(2) phase perturbations of the spin frames which do not show up in the spacetime tetrad. Gravitation emerges from PT-symmetric spin perturbations, whose path dependence shows up as spacetime curvature. We also predict a new "nonsymmetric" component of electrogravitation on particles with nontrivial electroweak form factors.
