Brigham Young says the governments of God and of men should be connected.
Brigham Young, as quoted in the entry for April 9, 1844, as found in History, 1838–1856, volume E-1 [1 July 1843–30 April 1844], p. 1993, The Joseph Smith Papers
We are acquainted with the views of Gen. Smith; the Democrats and Whigs and all factions. It is now time to have a President of the United States. Elders will be sent to preach the gospel and electioneer; the Government belongs to God; no man can draw the dividing line between the Government of God, and the Government of the children of men. You can’t touch the Gospel without infringing upon the common avocations of men; they may have helps and governments in Church, but it is all one at last.
