There is no provision in the rubrics for "an important politician".

Unless the deceased was a child or died after receiving the Apostolic indulgence or some other relief to the wages of life's sins, there is no reason to believe that she or he are "in the arms of God".

Be sure ... and I mean this with all my heart ... to tell your family and friends NOT to pray for you or seek indulgences for you after you pass away since you don't believe in Purgatory and will be "in the arms of God".
