The problem of national politics is its "one-size-fits-all" approach to governing. There is no room for diverse local populations to make independent decisions about their course of political development. Originally the nation was intended to be loosely governed from the national level, where such minimal governance as was necessary would be provided. National defense and interstate commerce were to be controlled to prevent invasion and internal warfare between the states. But the states were to govern their populations as independently sovereign states whose authority sprang from their people.
It is always best to "control" as little as possible and to interfere with development of separate ideas as little as necessary. This is true of government, and it is true of rearing children [after you have instructed them in the foundational truths], as well. It is also true of churches, civic organizations and any cooperative human endeavor. Cooperation through persuasion, meekness, kindness, pure knowledge and love unfeigned works, whenever it is tried. (D&C 121: 39-42.)
