Did the article say that it was official doctrine in the religion, I don't think it did.
I would say it’s part of the Mormon culture, but doctrinally...no, it’s been thoroughly “torn to shreds”, to to speak. It’s not even hanging by a thread, considering how it’s been lambasted by Church leadership for the last 100 years.
Mormons that actually research this, know this. The reason it’s culturally significant is that it borrows elements of truth, that LDS actually believe, that the Constitution will hang in the balance and need to be saved, partially by members of the Church.
Do I think it’s Romney? Not on your life.
Ezra Taft Benson, who was President of the Church and also served as Secretary of Agriculture to Eisenhower for 8 years while he was an Apostle, said specifically that the Constitution would not be saved in Washington. (see above quotes)
I think Washington, and by definition the Government, is toast. Get your food and ammo, it’s going to get ugly.
