"It was believed by many at the time that some of the [moderate] Republican Senators that voted for acquittal [of Andrew Johnson] did so chiefly on account of their antipathy to the man who would succeed to the presidency in the event of the conviction of the [sitting] president. This man was Senator Benjamin Wade, of Ohio, President pro tempore of the Senate who as the law then stood, would have succeeded to the presidency in the event of a vacancy in the office from any cause. Senator Wade was an able man … He was a strong party man. He had no patience with those who claimed to be [Radical] Republicans and yet refused to abide by the decision of the majority of the party organization [as did Grimes, Johnson, Lincoln, Pratt, and Trumbull] … the sort of active and aggressive man that would be likely to make for himself enemies of men in his own organization who were afraid of his great power and influence, and jealous of him as a political rival. That some of his senatorial Republican associates should feel that the best service they could render their country would be to do all in their power to prevent such a man from being elevated to the Presidency … for while they knew he was an able man, they also knew that, according to his convictions of party duty and party obligations, he firmly believed he who served his party best served his country best…that he would have given the country an able administration is concurrent opinion of those who knew him best."
