Tilden, who had prosecuted machine politicians in New York and sent legendary political boss William M. Tweed to jail, ran as a reform candidate against the background of the corruption of the Grant administration. Both parties backed civil service reform and an end to Reconstruction. Both sides mounted mud-slinging campaigns, with Democratic attacks on Republican corruption being countered by Republicans raising the Civil War issue, a tactic ridiculed by Democrats who called it "waving the bloody shirt". Republicans chanted, "Not every Democrat was a rebel, but every rebel was a Democrat."
