I know the sentiments to be found at the WSWS are not universally embraced here, but this is an article well worth reading (it was written, in part, by David North and I've yet to encounter anything with his byline that's a waste of time). The excerpt below doesn't do it justice, so if you have a few minutes, you might want to consider reading all the way through. And if nothing else, you'll enjoy the comparison of Kennedy's eloquence to "the political pig grunts" of the current occupant of the White House.

While many critical forensic questions remain clouded in mystery, the prevailing crises and divisions within America’s ruling elite provide the most compelling evidence that Kennedy was the victim of a state conspiracy, targeted by a faction of the ruling establishment itself in an attempt to shift the course of domestic and foreign policy. This crime had deep roots in the political climate of the time and far-reaching implications.

Nonetheless, the assassination of Kennedy was a political act whose aim was to shift the policies of the US government to the right. The conspiracy succeeded in accomplishing its aims. Moreover, it ushered in a period of politics by assassination that effectively eliminated some of the most effective leaders of the liberal wing of the Democratic Party and the mass movement for civil rights—Martin Luther King and Robert Kennedy.
Kennedy’s death marked the effective end of the Democratic Party as it had emerged from the New Deal. From 1963 onward, liberalism was dead on its feet. Increasingly, the policies of both major parties were marked by a shift to open reaction.
Present-day political life in America represents the victory of the very forces that were involved in—and celebrated—the 1963 assassination. The political underworld of CIA assassins, gangsters and criminal elements within the ruling elite with which the Kennedy administration worked behind the scenes have now come forward to openly claim the levers of state power.
