Establishing the national Democratic and Republican parties in Utah proved exceedingly difficult. Traditionally the Saints had leaned toward the Democratic Party because the Republicans, who had been in power most of the time since 1861, had promoted and enforced the anti-polygamy legislation. Furthermore, the Democratic-appointed officials of 1885–89 had been more lenient with the Saints. Considering the political tendency of Church members and the fact that most nonmembers in Utah were Republican oriented, the First Presidency wanted to avoid the Democrats becoming another Church party.
Meetings were held with stake presidents and bishops where they were instructed to encourage more Latter-day Saints to vote Republican. This would demonstrate to national party leaders that a viable two-party system could exist in Utah. Local leaders, however, were also urged to use good sense and caution in their encouragement. Church members who were known to have strong Democratic convictions were not asked to switch parties, but those whose commitment was not particularly strong were encouraged to change. This method was effective, and by 1892 the Republican Party was strong in Utah politics.
