In all these achievements the son shared with his father, and in some of them--notably in the obtaining of Utah's statehood--he had even a larger part than George Q. Cannon himself. When the Mormon communities, in 1888, were being crushed by proscription and confiscation and the righteous bigotries of Federal officials, Frank J. Cannon went to Washington, alone--almost from the doors of a Federal prison--and, by the eloquence of his plea for his people, obtained from President Cleveland a mercy for the Mormons that all the diplomacies of the Church's politicians had been unable to procure. Again, in 1890, when the Mormons were threatened with a general disfranchisement by means of a test oath, he returned to Washington and saved them, with the aid of James G. Blame, on the promise that the doctrine and practice of polygamy were to be abandoned by the Mormon Church; and he assisted in the promulgation and acceptance of the famous "manifesto" of 1890, by which the Mormon Prophet, as the result of a "divine revelation," withdrew the doctrine of polygamy from the practice of the faith. He organized the Republican party in Utah, and led it in the first campaigns that divided the people of the territory on the lines of national issues and freed them from the factions of a religious dispute. He delivered to Washington the pledges of the Mormon leaders, by which the emancipation of their people from hierarchical domination was promised and the right of statehood finally obtained. He was elected the first United States Senator from Utah, against the unwilling candidacy of his own father, when the intrigues of the Mormon priests pitted the father against the son and violated the Church's promise of non-interference in politics almost as soon as it had been given. It was his voice, in the Senate, that helped to reawaken the national conscience to the crimes of Spanish rule in Cuba, when the "financial interests" of this country were holding the government back from any interference in Cuban affairs. He was one of the leaders in Washington of the first ill-fated "Insurgent Republican" movement against the control of the Republican party by these same piratical "interests;" and he was the only Republican Senator who stood to oppose them by voting against the iniquitous Dingley tariff bill of 1897. He delivered the speech of defiance at the Republican national convention of 1896, when four "Silver Republican" Senators led their delegations out of that convention in revolt. And by all these acts of independence he put himself in opposition to the politicians of the Mormon Church, who were allying themselves with Hanna and Aldrich, the sugar trust, the railroad lobby, and the whole financial and commercial Plunderbund in politics that has since come to be called "The System."
