Tim Grieve, writing about impeachment, channels the same things I wrote even before we knew who Deep Throat was in A Democratic Congress will investigate Iraq:

Whatever it was, we were thinking about impeachment this morning, and when the first rumblings of the W. Mark Felt story broke, we started to ask ourselves: "Where are the 'Deep Throats' of today?" But the thing is, they're there -- and they're not hiding. They go by names like Clarke and Wilson, like O'Neill and Taguba. They've told us some of the stories, connected some of the dots. The Downing Street memo takes us a long way down one trail, but how much further could we go? What would a real investigation, one conducted by an independent prosecutor or a House impeachment committee, tell us about Saddam Hussein's WMDs? What would someone like Colin Powell say under oath? What would we learn about what Bush knew and when he knew it?

We don't pretend to know all the facts about Iraq, but we do know this: If Bill Clinton were still the president, there isn't a Republican in Congress who would say that the facts we do know don't warrant at least some discussion about articles of impeachment. It's not going to happen, of course. The Republicans won't let it, and the American people won't demand it; there's such a weariness now, such an acceptance that the administration misled us into war, that the nation is incapable of working up the outrage that would be needed to embolden the Democrats and overcome the Republicans' partisan opposition. But as the country moves past the final lingering question about the last president driven from office, isn't it time to at least start asking serious questions about this one?

Amen.
