Hitler died 4/30/45, and Trump was born 6/14/46. If you go with the Tibetan schedule - die, wander the Bardo a few months, enter a fresh fetus, gestate, get born - it works out about right. Ditto for Mussolini, who died two days before Hitler. Though I would imagine the karmic demotion that would follow a life like either of those dictators would involve returning as someone subjected to more suffering.
