Student deferments ended in Sept. 1971 . Trump graduated in 1968 which means he could have gone for his Masters and got another deferment . BTW , I was 19 in 1971 . My number was 140 . Fortunately for me the highest number they took was 95 .
I graduated HS in 1974. They still had the supplemental draft list going by birthdate. Mine was #8 but the war was all winded down by then—otherwise I would have been drafted.
