Bummer! Now there are only two secrets left: Where's Jimmy Hoffa? And what was the runaway bride really up to in Las Vegas?

The unveiling of Deep Throat was, for most of us, a big letdown. First, because it ruined the best and longest-running cocktail party chatter in American politics. But also because, after all this speculation for so many years, he turned out to be 91-year old Mark Felt of Santa Rosa, Calif. – somebody few of us had ever heard of, let alone suspected. How much more fun had he, in fact, turned out to be Henry Kissinger or Alexander Haig.

Felt's coming-out party – orchestrated by his family, with the help of Vanity Fair magazine – was a godsend to talk radio and cable television and a welcome distraction from the sordid Michael Jackson trial. But, as usual, I think the media missed the big story.

Most Deep Throat coverage focused on one of two angles, starting with: Do you believe he's the one? That question quickly ran out of steam when the Washington Post's Bob Woodward, Carl Bernstein and Ben Bradlee, official keepers of the secret, admitted that Felt was their man – and that they'd been scooped by Vanity Fair.

Then followed the second, equally fatuous, question: Is Mark Felt a hero or traitor? No surprise that Pat Buchanan and G. Gordon Liddy – the only two Nixon lovers left on the planet – were alone in branding Felt a snake. Nixon was a crook and a liar and a man who used the powers of the presidency to undermine the Constitution. Anybody who was brave enough to stand up and expose Nixon's wrongdoings, no matter his personal motives, is an authentic American hero. Too bad there aren't more like him today.

And that's the big story of Mark Felt's confession. Not: Why did he dare tell the truth about Nixon, way back then? But: Why doesn't somebody tell the truth about George W. Bush today? Where's Deep Throat when we need him, now more than ever?

As bad as they were, Nixon's crimes weren't the worst committed by an American president. Indeed, former White House Counsel John Dean – another hero for warning Nixon about a "cancer growing on the presidency" – argues that George W. Bush is very much like Nixon in his penchant for secrecy, only worse. In his book, "Worse Than Watergate," Dean wrote:

George W. Bush and Richard B. Cheney have created the most secretive presidency of my lifetime. Their secrecy is far worse than during Watergate, and it bodes even more serious consequences ... I must say this administration is truly scary and, given the times we live in, frighteningly dangerous.

But the only way to blow the lid off the misdeeds of the Bush administration is to come up with our own Deep Throat. Somewhere in the Bush White House, for example, there is someone who knows the list of special-interest lobbyists who met secretly with Cheney to develop the administration's energy policy.

Somewhere in the White House, CIA or Pentagon, there's someone who was present when Bush and Cheney decided to lean on a pack of lies – about nuclear weapons, weapons of mass destruction, chemical-laden drones, mobile weapons labs, long-range missiles and Saddam Hussein's ties to al-Qaida – in order to sell the American people on the war in Iraq.

Somewhere in the State Department, there is one federal employee who knows why President Bush won't release key documents about John Bolton to the Senate Foreign Relations Committee. Others inside the administration could unlock still more secrets. Who approved the orders to torture Iraqi prisoners of war? How many prisoners have been "outsourced" for torture by other countries? Who decided to leak the identity of undercover CIA agent Valerie Plame? Did Bush ever report for National Guard service in Alabama? With Bush, as with Nixon, we'll never know the truth until one or more brave souls are willing to speak out.

So now we know who Deep Throat is. Big deal. It means nothing, unless Mark Felt inspires Bush administration insiders to go and do likewise. Blow the whistle. Tell the truth. Expose the evildoers. Make your country proud.

Any new source's success, of course, will depend on finding reporters courageous enough to dig for the truth, and not simply regurgitate White House propaganda. Sadly, that may be a harder task than finding another Deep Throat.
