The year which has passed since the preparation of the last “Notes on Municipal Affairs” (June 1, 1930) has been even more eventful than the preceding period.Developments in Particular Cities. New York City. The belief which had been growing for many years that the Tammany tiger was, after all, a self-restrained, self-muzzled beast has suffered a rude shock in the exposures of flagrant corruption in the sale of judicial office, the handling of vice, the purchase of land for school purposes, and in many other directions. The district attorney's office has been exposed to the searchlight of investigator Seabury. Charges were preferred against Mayor Walker by John Haynes Holmes and Rabbi Wise in the name of a citizens' committee. Governor Roosevelt dismissed these charges with scant consideration. In the meantime, however, the legislature ordered a most searching investigation of the whole governmental situation in New York—an investigation which bids fair to rival, in extent and dramatic interest, that of the celebrated Lexow committee.Chicago. In Chicago, Mayor Thompson's political career has suffered, if not extinction, at least a total eclipse. Though victorious against a broken field in the Republican primary, he was defeated by Anton J. Cermak in the election of April 7 by a vote of 476,932 to 671,189. It is probable that the people of Chicago were more anti-Thompson than pro-Cermak, but the new mayor is a vigorous and striking figure. For one thing, he is boss in his own right of the Democratic organization in Cook county.
