The campaign focused on the candidates' personalities, as each candidate's supporters cast aspersions on their opponents. Cleveland's supporters rehashed the old allegations from the Mulligan letters that Blaine had corruptly influenced legislation in favor of railroads, later profiting on the sale of bonds he owned in both companies. Although the stories of Blaine's favors to the railroads had made the rounds eight years earlier, this time more of his correspondence was discovered, making his earlier denials less plausible. Blaine acknowledged that the letters were genuine, but denied that anything in them impugned his integrity or contradicted his earlier explanations. Nevertheless, what Blaine described as "stale slander" served to focus the public's attention negatively on his character. On some of the most damaging correspondence, Blaine had written "Burn this letter," giving Democrats the last line to their rallying cry: "Blaine, Blaine, James G. Blaine, the continental liar from the state of Maine, 'Burn this letter!'"
