A law for the Sunday closing of saloons had been passed under Foraker; when Cincinnati mayor John B. Mosby proposed to enforce the law against local opposition, Foraker wired to Mosby the support of the state government. This stance alienated many anti-Prohibition Republicans. Another damaging incident was Foraker's claim, based on documents he procured that turned out to be forged, that Democratic gubernatorial candidate James E. Campbell had supported the adoption of a ballot box made by a company in which Campbell supposedly had a financial interest. The documents also bore the signatures of Sherman, McKinley, and other Foraker enemies; they were later shown to have been taken from franked mail. Campbell was not in fact involved with the company, and the affair cost Foraker votes. A congressional committee conducted an investigation in 1891 and cleared all of those whose signatures had been reproduced. However, it blamed Foraker for using the documents without verifying their authenticity. By then, Foraker was no longer governor, having been defeated by Campbell by 10,873 votes out of some 750,000 cast. McKinley biographer H. Wayne Morgan noted, "Clearly Foraker acted hastily and unwisely because of his desperate fight against Campbell and his bitterness towards the Shermanites." The defeat had consequences for Foraker; according to another of McKinley's biographers, Kevin Phillips: "when Foraker lost his bid for a third statehouse term, McKinley became Ohio's next-in-line presidential favorite son".
