Let's play the George HW Bush game.
Herbert Hoover: Bush's grandfather was an economic adviser
FDR: Bush's father got busted trading with Nazi Germany during WWII, but FDR decided it would be bad for morale to lay down the law
Nixon as VP: Bush's father is credited with starting Nixon's political career, and having him chosen as Ike's running mate
Bay of Pigs: One word, Zapata
JFK: For some reason he can't remember where he was when JFK was assassinated. Nixon had that problem too, until someone reminded him that he was in Dallas.
Nixon as VP: When Bush was ambassador to the UN, we almost went to war with India
Ford: Bush claims that he wasn't part of the CIA until appointed head of it by Ford. Does anyone actually believe that?
Reagan: Decided to be Voodoo's running mate
