At the state convention at Pocatello in 1904, Borah made a speech in support of the election of Theodore Roosevelt for a full term as president, which was widely applauded. But the Old Guard Republicans in Idaho opposed him and they were determined to defeat Borah in his second bid for the Senate. The same year, Dubois damaged his prospects for a third term by his opposition to the appointment of H. Smith Woolley, a member of The Church of Jesus Christ of Latter-day Saints (many Idahoans adhered to that faith), as assayer-in-charge of the United States Assay Office at Boise. Dubois had advanced politically through anti-Mormonism in the 1880s, but the issue was more or less dead in Idaho by 1904. Woolley was confirmed by the U.S. Senate despite Dubois's opposition, and Rufus G. Cook, in his article on the affair, suggested that Dubois was baited into acting by Borah and his supporters. The result was that Borah attacked Dubois for anti-Mormonism in both 1904 and 1906, which played well in the heavily Mormon counties in southeast Idaho.
