Just because your paranoid ...
Many lightly dismiss the notion of the Bushies canceling (delaying) the election in light of a terrorist attack because they just can't imagine that our leaders would ever do such a thing.
Just like they never imagined our leaders would lie us into a unilateral, pre-emptive war and deliberately feed on our fears of terrorist attacks for partisan political gain.
Now I am not saying I buy into the "cancel the elections" idea. I'm just saying that "they wouldn't go that far" is not a sufficient refutation of the idea.
