The Ohio voters chose a Democratic state legislature, however, which selected Thurman as senator for the term beginning in 1869. He there became a strong opponent of the Republicans' Reconstruction measures. In 1873 Thurman crafted a strategy that led to Ohio choosing once more a Democratic legislature, and electing Thurman's uncle William Allen as governor. The legislature elected Thurman to another term in the Senate. During the twelve years he served in the Senate, he became the leader of the Democrats in that body. He was known for constant hard work, good preparation, and courteous treatment of his opponents, and other members ranked him among the top three senators of his time, in terms of ability. He came nearest, a Washington correspondent concluded, to "the beau ideal of a Senator of any man on his side of the House. He has fine passing power of cutting up his political opponents, saying a word of encouragement to some Republican when he is down, and scattering the caucuses of the opposite side with a pistol shot." His prepared speeches were clear and cogent, but it was in debate that he showed himself at his most picturesque. "He would wave his red bandana pocket handkerchief like a guidon, give his nose a trumpet-blast, take a fresh pinch of snuff, and dash into the debate, dealing rough blows, and scattering the carefully prepared arguments of his adversaries like chaff," a Washington long-time reporter remembered. He kept up a close friendship with his chief sparring partner on the opposite side, George F. Edmunds of Vermont. Journalists told how at a given signal—a long blow of his nose—he would get ready to exit the Senate so that the two could meet in the Judiciary Committee room to share a liberal amount of Kentucky Bourbon.
