the difference was that Clinton was the current President and the other 4 were all past Presidents and were retired.
this one is of 3 future Presidents. All of the same party, all of whom would serve in the order you see them. 3 guys who would define their party for the next generation, who would largely define their country, who would largely define the world for the next generation.
