Since the Constitution did not explicitly indicate how Electoral College disputes were to be resolved, Congress was forced to consider other methods to settle the crisis. Many Democrats argued that Congress as a whole should determine which certificates to count. However, the chances that this method would result in a harmonious settlement were slim, as the Democrats controlled the House, while the Republicans controlled the Senate. Several Hayes supporters, on the other hand, argued that the President pro tempore of the Senate had the authority to determine which certificates to count, because he was responsible for chairing the congressional session at which the electoral votes were to be tallied. Since the office of president pro tempore was occupied by a Republican, Senator Thomas W. Ferry of Michigan, this method would have favored Hayes. Still others proposed that the matter should be settled by the Supreme Court.
