What if he leaked some information and only thinks that he is DT? I think that it's credible that DT was an amalgam of credible leaks to the WaPo.
Anything the democrats can do to keep Nixon and Watergate alive they will do. Clinton, by far, committed worse deeds than Watergate. The only problem is, the media won't report it. After all, don't you see, he is a democrat. Only Republicans get smeared.
Your right, he and his family are going to look pretty foolish if they claim him to be DT, and have Woodward turn around after his death and deny it.
