Several thoughts:

There are so many folk out there who weren't around for the head trip many of us were of age to remember called Watergate. We are also entering a new era with its own threat scenario and new global issues. So this revelation comes right on the edge of who cares-ville. Apparently those who were up on the niceties of the Watergate era knew who he was and that he might be a contender for the leaker.

Also, he's of an advanced age and this is his last hurrah, his last chance to put a little spin on his reasons for giving Administration insider help to Woodward & Bernstein.

Still, its nice to remember an era when a free and independent news organization could defy a powerful Administration which kept a serious enemies list.
