What it says on the label. Could Sean Carter of Queens, New York, become politically active as a young person and eventually become a Republican politician? His music OTL seems to often be anti-government, and his rags-to-riches story might make him more open to the ideas of market-based solutions to poverty and economic inequality in black America.
For the AHC, he doesn't necessarily need to become a rapper, but some involvement in the music industry would be good. Being a rapper would be a major bonus though. The world events of his childhood and adolescence should be similar to OTL.
