In the spirit of a related inquiry, I would like to know if there's a basis for understanding why there aren't any elementary particles that have non-zero electric charge but zero spin?

Can such a quantum theory be written down and self-consistent? Do the current symmetries of our present QFTs not allow such a particle?
