2000 Without Nader?

[Mr. Morden]

2000 map with Gore winning Florida and New Hampshire.

Dubya goes into political obscurity, 9/11 never happens.

Al Gore being elected prevents al Queda from attacking NYC?...  Okay...

He reads the intelligence reports and acts appropriately.

And what "appropriate" action by the president would have led to Mohammed Atta getting caught?

[Mr. Morden]

I don't think 9/11 would have happened under Gore, because I doubt he would have ignored the warnings as Bush did.

What, specifically, would he have done that would have led to Mohamed Atta getting caught?

No one can say for sure that 9/11 would not have happened under Gore, but I do think that warning signs would not have been ignored.

You're not actually answering the question.  What was "ignored"?  The vague "Osama bin Laden" wants to attack us" warning?  Hard to see how things would have played out any differently unless you have a specific idea for what the alternative course of action would have been.
