Query: 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.
