By 1899, the Republicans were back in the majority in the General Assembly and another U.S. Senate seat came vacant. In 1901, the second one became vacant as well. Now Delaware had two seats vacant and still the General Assembly could not elect anyone. The situation was drawing national attention, and ridicule. Finally, the "Regular Republicans" issued an ultimatum to Allee, saying they would cooperate with the Democrats unless Addicks would relent. Under much pressure, Addicks did finally compromise by allowing his lieutenant, Allee, to be elected to one of the U.S. Senate seats on March 2, 1903. By the time Allee's term ended, Addicks had lost his fortune and left Delaware politics. T. Coleman du Pont became the effective Republican leader and managed to bring the two competing factions together. Without his mentor, Allee was politically stranded, and therefore, was not a candidate for reelection when his term ended.
