It may be they just covered it up. The meme was that terrorists were what we now call bitter clingers, or potential "terrorists" if you work for DHS.
Having little problems like muslims trying to blow up the WTC, or maybe being involved with a bombing in Oklahoma, or shooting down aircraft just didn't fit the pattern--and would have caused the stovepipe of the Gorelick Memo to be hauled down--possibly exposing some of the Clinton's own nefarious deeds.
They couldn't go there.
Now, with the (dangnear) whole kit and caboodle composed of either fellow travelers or the hideously compromised, the enemies of this country have grown ever more brazen in their actions, secure in the idea that they have THE dirt on everyone who has any, the media in their pocket, and the ability to destroy careers at will if anyone gets out of line.
Which, incidentally, is why they hate the TEA Party. People without background data assembled already make them scurry for crap to sling--if they can find any.
The ranking 'pubbies are likely told to do all they can to beat such folk (unfunded, underfunded campaigns, etc.), or they might get taken down, too. My bet is McCain lost because Gov. Palin was dangerous to them all (even the 'pubbies attacked her or fed the data out to try to do so).
Do you remember Jose Padilla, the Hispanic Islamist terrorist? Go back and look at the sketches of "John Doe #2", the person allegedly with McVeigh when he bombed the Murrah Building. The look almost exactly like the sketch of Padilla.
Could that be why the "authorities" finally tried to tell us that John Doe #2 didn't exist? Did they know who he was?
