Robert suggests a new kind of discussion for us, an "alternative history". We wrestle with the question: what if Robert Kennedy isn't killed in June 1968? Does that alter America's trajectory through the 1970s and 1980s? Bonus feature, we have to edit out our first "f bomb". Francis, watch your mouth next time. 

Once again, the guys did not mention it here, but still one of the better biographies of Robert Kennedy is one of the earliest, Robert Kennedy and His Times by Arthur M. Schlesinger and Michael Beschloss, originally written in 1979 but recently reissued in 2012.

Also if you really want to read some great "alternate history" novels, the guys suggest anything by Harry Turtledove, perhaps one of the acknowledged masters of the genre.
