You da' Boss!!
I think the real point of the Press Conference (for McGreevey's sake) was to diffuse the Sexual Harassment suit, given the Governor's admittance of having "Consensual Sexual Relations" with another man. From the "management side", it gave McGreevey an (albeit weak) excuse to leave office. I believe that it was decided months ago that McGreevey never had a chance to be re-elected. The "machine" had to get rid of him, but he was a stubborn little prick. Had this "Gay Affair", not done the trick and got him to resign, who knows what would be made public next? Considering how many "bad" deals McGreevey has made in the past, I think the "machine" could just keep pulling one out of it's hat every week, until McGreevey wound up committing suicide. Who knows which member of his family was going to be the next target?
Through all of this, there is one thing for certain: McGreevey had to go, and he had to go fast (before that Sept. 15th deadline). That's the way the people in control wanted it - and that's the way they were going to get it!!
Politics in NJ has a lot of parallels with the Sopranos (which is incidentally shot (no pun intended) in NJ). There is even speculation as to exactly how the Governor broke his leg a couple of years ago, while supposedly walking along the Jersey Shore. I've been walking along the Jersey Shore for close to 50 years, and I've never even sprained an ankle!?! Just some food for thought.
