I'd add several comments about following the money.
The comments about the money on the left (pointed out by Daiwa) are dead on. The MSM (main stream media) has absolutely no interest in following that money. For example, the huge pile of money that Soros spread around all over the place, nah, no interest. The pile of money that Amnesty International and it's friends gave to the Kerry campaign, nope no interest. The uncounted piles of money that was raised for Hillary and friends of Bill & Hillary? No interest in where that came from either, or how it was accumulated.
The part of this story that starts putting Mark Felt into the traitorous sleazebag category is his family. They were the ones behind the "outing." They know the old man is sliding fast, and they want to cash in while they can. There are quotes from Felt himself reportedly saying that he had come around to believing that people had come to see him as a hero.
Some additional comment here, hearsay if you will....
I was listening to Tony Kornheiser's radio show the day after the news came out. He had one of his usual (regular) guests on, John (Jr.) Fienstein, former Post writer (as is Kornheiser for the most part) and Fienstein went into a story about how this news almost came out back in 1999. According to Fienstein's story, Felt had told Woodward that he could go ahead and release the info on his identity. The problem was that Felt was already showing signs of dementia, and was not able to remember details that would have proven to the world he was who he claimed to be. Woodward apparently made the decision that he couldn't be sure that Felt was "of sound mind and body" in giving permission to release his identity and terminate the original agreement he had made with the Washington Post, Woodward & Bernstein and their superiors. So Woodward sat on the story.
If that story is true, and hell, even if it's not, I do have to respect the Post, Woodward and Bernstein, and the others involved that kept their promise and never told the public who Deep Throat was until after the identity was released to the public elsewhere (thereby ending the original agreement).
The Washington Post provided some history in various columns about how the news that was out in print in Vanity Fair almost didn't come to be. Apparently the person that was selling the story to Vanity Fair was trying to do just that. VF turned it down initially, refusing to pay for the story. From there, a book was going to be assembled instead. The book apparently didn't find a publisher/distributor, and the story wound up back in VF's hands.
As I've clearly heard quotes from the family, the family felt it was time to "cash in" on the notorieity of the long kept secret. Again, in my mind, taking away any chance to try to be a hero, and instead showing Felt to be someone who was mad that he was passed over and who instead took to providing information to the Post, rather than going to Congress. All the more making it seem to me that Felt was being greedy, and was trying to pay back the Nixon administration for being passed over.
What if Felt hadn't been passed over, and had gotten the top job at the FBI, would Deep Throat have existed at all, and would we even care about Watergate?
One other comment here, can those that remember watching All The President's Men not get over an eery feeling that the people that made the movie just about outed Felt through their choice of actor for the role? Single individual, male, etc. Holbrooke fit the description fairly well, but also bears a pretty decent resemblance to what Felt looked like during the the time of the story.
