Who believes Mark Felt was the "Deep Throat" of Watergate?

Question

I've read articles where he claims to be "Deep Throat".
However, I've also read articles that dispute his claims. Some of the timelines presented by detractors make sense when compared with the events chronicled in "All the President's Men".
I've read an article where Woodward confirmed Felt's story in Vanity Fair.
But, I could see Woodward going along with this as Felt at the time was 91& ailing.
Will we ever know for sure?

Answer 1

I believe afterall we should believe everything that is passed off as fact from Washington DC right?

We'll never know for sure, add that to the list:

1) JFK assassin
2) What caused TWA 800
3) Did the Egypt Air flight land at Edwards AFB as "confirmed" by CNN?

etc...
