We show that recent radio and optical observations of polarized radiation from well-resolved high redshift quasars and radio galaxies rule out the cosmological rotation of the plane of polarization claimed recently by Nodland and Ralston. A least squares fit to the radio data has a slope only 2% of their claimed effect.
Comments: This is a revision of a paper submitted to Phys Rev Letters. A number of modest changes have been made, including using more radio data, really replacing the optical data on Cygnus A with that on 3C265, and adding to the discussion. Three pages and three figures
