That's the thing; they're NOT "suddenly appearing." They've been around all along. It's just that in the entire two-and-a-half-year history of the Bush Administration thus far, this is the FIRST ginned-up pseudoscandal to come along that both: a) has had legs, and b) is complex enough to allow the leftists and haters to play semantic games and argue basically anything they want from any direction. It's Tenet's fault! No, it's Blair's fault! No, it's Bush's fault! They're throwing dozens of different, mutually exclusive attacks out there at the same time, hoping to God that one of them sticks.
These people have been praying for something like this to come along since January 2001. Now they've got it. And I hope they're enjoying themselves, because the news media is already starting to hit brick walls with the story, which means it's not going to be around much longer. Example: On Sunday, AP radio news at the top of the hour had this as their top story, and was devoting two entire minutes to it; that's a LOT for a six-minute newscast. By Monday afternoon, ABC Radio didn't even have it as their top story, and they ran maybe thirty seconds. I haven't watched or listened to too much news yet today, but what little flipping around I've seen on the cable channels has been mostly about hurricanes and murders and abducted children.
Barring a major new leak from some leftover Clinton kneepadder (which probably wouldn't even be true), this story simply has no place left to go. Bush has explained himself, so has Tenet, so has Blair (and, most importantly, British intelligence). All that's left now is for the RAT presidential candidates to continue getting bolder and bolder in their attacks on the President, which will help them in the next few days ... but for which they will end up paying in millions of lost votes in 2004 once the truth finally shakes out and they're left looking like the opportunistic, soft-on-national-security, Bush-haters with nothing to offer but fear itself, that they are.
