Just finished reading "If Kennedy Lived: The First and Second Terms of President John F. Kennedy: An Alternate History" by Jeff Greenfield. Pretty interesting premise; begins with the weather in Dallas not clearing up and the presidential limo keeping the "bubble top" on, which allows JFK to survive the one shot he sustained...
I've read a similar book about Bobby Kennedy surviving his assassination and becoming president in 1968, but that was a fawning fantasy by a terrible amateur author. Greenfield is a erudite journalist and author, and this stuff is well-researched and cited in the last chapter-- his alternate history is not just some flight of fancy, there's a lot to back it up.
It gets a little cutesy at times with foreshadowing (a young Al Gore. Jr. telling his dad, " Makes sense --you can't expect to be elected President if you can't carry your home state"; Barry Goldwater suggesting that "some enterprising person may start a private delivery service that would give the Post Office a run for their money"). And, despite his credentials, I think that Greenfield falls a bit to the typical feel of his generation, that, "if Kennedy had lived, everything would not only be different, it would have been GREAT".
But it was overall a good read.
