Is the doubler of the electron an antiquark?

Reassigning degrees of freedom in the standard model allows an interpretation where the SU(2) gauge group is vector-like and parity violation moves to the strong and electromagnetic interactions. In this picture, the electron is paired with an anti-quark. Requiring exact gauge invariance for the electromagnetic interaction clarifies the mechanism behind a recent proposal for a lattice regularization of the standard model.
