I think Scott McClellan, being who he is and his long-standing relationship with George Bush, in writing this book is essentially "breaking the ice" on this frozen sea of an Administration. In other words, he is the first domino in what could be a "domino-effect" of others within the Bush administration to come out with their own "tell-all" books. 

He of course gets the big pay-day for being the first "insider" whistleblower, but with it also comes all the withering attack of arrows and mud that will come flinging in his direction.  But seeing as how he was a press secretary for the highest office in the land in one of the most deceptive and manipulative Administrations in history, I am sure he is training will allow to spin his side effectively -- making him an ideal frontline attacker. 

McClellan essentially gives cover for all the other insiders itching to get their stories out to the public and will make it a much less dangerous proposition so with that in mind, who do you think is next?

I think Colin Powell is the obvious candidate, because of the precipitous fall of his stock since the war. But how about something out of left-field like Condi Rice?  She looks like she might be someone who gets troubled by demons. 

Any other guesses?

Hillary Clinton might very well ruined her Presidential Campaign in 2008 and quite possibly any campaign in the future because of her RFK comment a la Mike Dukakis, Howard Dean, John Kerry et al.  She has no doubt lost a good deal of clout and standing in part because of this gaffe, but also because of a lot of ill will built up throughout her campaign.  This could very well be the low point of her personal political career --

Which is why Obama should offer her the V.P. spot NOW.

I can't take credit for this idea.  In a fit of genius, Jonze wrote this in the comments section of the Assassin's Gate post:

In a crazy way I think this could actually increase the chance that Hillary would be on his ticket simply because it would be seen as 100% his choice now. Before this incident it would always be seen that he was forced into having her as his VP one way or the other meaning he couldn't possibly choose her without the prevailing belief being he bowed to pressure. However now he has the out if he didn't want her and nobody could really object, so if she did end up on his ticket it would be seen as his choice and not any weakness.

I agree with this sentiment.  I also find that in history sometimes the greatest of rivals turn out to be the greatest of friends:  You always expect your friends to help you. But if in a time of great need a former enemy comes to your aid, the impact is all the much greater and the bond that forms is all the more stronger.  Jonze is right that Hillary is now in a very weak position.  Reading this NYTimes blog post account of the entire incident, you can tell that Hillary realizes that she really screwed up big time.  You can can see it in her face and hear it in her voice and in the desperation and dejection of even her most rabid supporters. Its palpable:  This is Hillary's "Macaca Moment".    She is no longer in a position to dictate much of anything nevermind her place on a presidential ticket.  She is emotionally and politically exhausted.

The entire MSM is piling on her.  Everyone is basically pronouncing her Vice Presidential aspirations dead in the water.  Her stock is at an all-time low, and everyone is bearish on her and selling -- which is why this is the moment Obama should be buying.  Hillary's best chance of redemption is getting the V.P. spot and Obama has a chance to pick up a valuable ally at an extremely inexpensive "price".

"Nobody expects the Inquisition!" 

...and nobody will be expecting Obama to  offer her the Unity Ticket.  It will be shocking, dramatic and it will create the perfect "Hollywood ending" to the climax and denouement of this totally "made-for-Hollywood" Democratic Primary. The media and country will drink it up like milkshake.  I know I certainly would be moved by such a magnanimous act of reconciliation.  I can even picture the VP announcement "scene" at the convention with the inspirational music (like Jerry Goldsmith's score from the movie "Rudy") and confetti and the eruption of cheers from crowd as Obama and Hillary stand side-by-side waving to amidst the flashes of the camera bulbs.   They will make movies and write stories about this Democratic primary for years to come.

Its almost too perfect an ending as to seem scripted.  And you know the Republican conspiracy theorists will build a whole cottage industry around this if it does happen.  But it creates an amazing narrative that could inspire the entire country if not the world.
