More than just Utah and possibly more than just cultists.
An very possible ulterior motive for Mormons who openly or secretly support the Open-Border agenda is obviously suggested by: 1) Mormon history and 2) The distribution of the Mormon population in the US.
1) Their history includes a mass exodus exodus from the US to settlements in colonies in Mexico, when statehood required them to outlaw bigamy. Mitt Romney's father (Governor George Romney) was born in such a colony in Mexico. Most only returned decades latter when a Mexican revolution made conditions too dangerous.
2) A map of the Mormon Corridor sidling up to the Mexican border raises questions of the Mormon Church's long term policy intentions regarding separate arrangements with Mexico.
