While hardly a Republican apologist, I find it interesting that the Clinton/Lewinsky scandal did not surface until Starr spread his net far beyond his official purview. Most of the others came out in the curse [sic] of "normal business." Yes, Clinton's behavior on this issue was reprehensible. The goal of the persecution, though, was an effort to force him to resign or be impeached over anything that could be used as a lever.

Kennedy's infidelities were well known. The fact that they have surfaced again is probably an artifact of the start of the electoral season--"See, all them Democrats are secretly screwing everyone." There is probably an element of envy in addition to tar in all that publicity.
