At the 1872 Democratic National Convention , Stevenson received the votes of Delaware 's six delegates for the Democratic vice-presidential nomination , although Benjamin Gratz Brown was ultimately nominated . In February 1873 , Vice-President Schuyler Colfax named Stevenson as one of five members of the Morrill Commission to investigate New Hampshire Senator James W. Patterson 's involvement in the Crédit Mobilier of America scandal . Stevenson and fellow Senator John P. Stockton of New Jersey both asked to be removed from the commission , but the Senate refused to grant their request . On February 27 , 1873 , the commission recommended Patterson 's expulsion from the Senate , but the chamber adjourned on March 4 without acting on the recommendation . Patterson 's term ended with the end of the session , and he was not re-elected , rendering moot further consideration of the matter
