I don't think that it's Mark Felt.
Mark Felt doesn't smoke.
Pause
If it's Felt, then Woodward and Bernstein have been caught in a smoking lie that will discredit much of what they wrote.
My money says:
1. It isn't Felt,
2. Woodward and Berstein will go silent about this new Vanity Fair article.
Woodard and Berstein aren't commenting on Felt and the Vanity Fair article, so you're right about that. If Deep Throat is Felt, why wouldn't Woodard and Berstein confirm that after Deep Throat outed himself?
I still think Deep Throat is Al Haig but we will find out sooner or later when Woodard and Berstein reveal Deep Throat's identity.
A page I just read from a link I ran across on FR just now (I'll look it up) said that one of the editors or something at the Post thought that he probably made the smoking part up because he tried so hard to hide DT's identity and because they made such an over the top deal out of the smoking part.
