The implications of the recent measurement of the left-right asymmetry ${\mathit{A}}_{\mathit{L}\mathit{R}}$ by the SLD Collaboration for theories with extended gauge sectors are examined. We show that it is possible to arrange for large, negative values of S, based on an analysis of leptonic data, without serious side effects for other …
