(Well, not yet...Ann Romney has MS. Per this source, MS, the life expectancy of people with MS is 5-10 yrs lower than unaffected people...If Mitt became a widower...and remarried another Mormon "for eternity" in the Lds temple...then, per Lds doctrine...Mitt would become an eternal polygamist at some pt beyond death)
