Democrat Louis L. Goldstein, a Maryland institution, has been comptroller since 1958. This longevity gives the revenue office stability and expertise. Mr. Goldstein runs an efficient shop and has kept a close eye on tax receipts, pension-fund investments and Board of Public Works activity. Republican nominee Larry M. Epstein is a spirited challenger but hasn't found any major chinks in Mr. Goldstein's formidable armor. We endorse Comptroller Goldstein's bid for a ninth term.
