Then Everything Changed: Stunning Alternative Histories of American Politics: JFK, RFK, Carter, Ford and Reagan

This was a quite interesting speculation of how historical events might have gone but for a twist of fate. What if the suicide bomber actually struck JFK right after his electoral victory and LBJ was in charge during the Cuban missile crisis? What if Sirhan Sirhan had missed Robert Kennedy? What if Ford had managed to defeat Carter in 76? This is just the thing for political and historical junkies who enjoy "What if...?" scenarios.
Unlike a lot of alternate histories written (I'm looking at you, Turtledove!), this was well thought out and each speculative scenario quite plausible.
