The truth of "deep throat" is that top FBI agents played two cub reporters for suckers.
The Washington Post didn't do outstanding investigative reporting, they just sat still while powerful men who majored in corrupting the human spirit used them.
The WaPo kept two cub reporters on the story because if it blew up they'd be easy to sacrifice. By late spring '72 it was clear Nixon was going to be reelected, probably in a landslide. The Dems and WaPo were waiting until after the election for their senior people to come in and begin the hunt for Nixon. Their only concern (and it was a big one) was about puting Agnew in the White House. That was taken care of when a local Republican (liberal) prosecutor in Maryland received information that the Vice President had been taking illegal payoffs from contractors while governor of that state. In 1973 the Grand Jury in Maryland begins investigating Agnew, and with his resignation only a matter of time, the Watergate investigation begins to get heated up in the Senate. Someone should look into the Agnew case, I'd bet they'd find some strange stuff.
Once the Senate (remember that great protector of liberty, Sam Ervin (racist)?) and the Big Media outlets took over, Nixon was cooked. Those were the days when the MSM could and did set EVERY agenda. Look, Nixon WAS guilty of a coverup. That's not the question. The question is: did he do anything other administrations had not done and did he deserve to go down for it? Read Conrad Black's "FDR"; Black says that compared to the secret stuff FDR had the IRS and FBI do, Nixon was a saint. THERE IS NO QUESTION THAT BIG MEDIA USED A HUGE DOUBLE STANDARD IN COOKING NIXON.
