Bad news in the new Zogby poll, at least if your name is Bush. Not only was there no bounce in Bush's speech, but the red states have turned against him and 42% of voters say they'd want congress to begin impeachment proceedings if only they knew about the Downing Street Memos. That's not going to happen, of course, not with a Republican majority. But if the media was serious about pushing the story in the way they pressed Whitewater, it'd prove a real danger to the administration.
The very fact, however, that Zogby is polling questions of impeachment shows that the memos are gaining traction. This is the sort of thing the media loves to report: numbers, information, artifacts that make their stories look driven by news rather than editors. And 42%, for that matter, is a very high number. How many media organizations pick up on it and how hard they push it will say a lot about how constant media coverage is between administrations.
