In 2000, press analyzed Gore's charisma-challenged personality by saying he was a beta male who hadn't yet learned to be alpha, as evidenced by his choice of earth-toned clothing. The press was wrong, as usual. Gore's problem had nothing to do with being cowed too easily, or a lack of self-esteem.
Gore was also described that election year as being a bit of "a wooden Indian," which was a lot closer to the mark. He's just awfully stiff. Even walking and gesturing don't seem to come naturally to him. He moves like someone who has just been taken out of a box.
Gore comes across like a robot who's learned how to act like a human being from a book. After painstaking study, he now does a passable imitation. But really, it's only just passable. (And the robot does seem inordinately proud of that second-rate imitation.)
Think of how he speaks, in that slow, slightly overemphatic, pedantic tone. He always sounds as if he's explaining something to a group of particularly backward third graders.
Another trait of people with Aspergers is that they are very rigid in their beliefs. While there are respected scientists on both sides of the global warming argument, Gore obviously believes in it as if it is established fact. And he gets becomes infuriated at anybody who doesn't believe in it -- as a true Aspie would.
Despite all of Gore's preaching, he himself lives in a sprawling house in Tennessee whose carbon footprint is famously twenty times that of the average citizen's house. He takes private planes and drives around in an SUV. Hypocrisy of course does not prove Aspergers, but tone deafness is an indicator. And being unaware of how you come across is one of the essential components of Aspergers.
I once heard another Aspie say that her child had to go to the right school "in order to earn social skills." This is a prototypically Aspergerian belief, that learning the social niceties and how to get along with others is something that you would need a school to teach you. Normal people pick up social skills through trial and error wherever they grow up, and whomever they interact with. Only someone with Aspergers would believe that you have to be "taught" how to say hello, how are you, and so on.
Now that I think of it, a specialized school just for people with Aspergers actually wouldn't be such a bad idea. Such a school might teach its students to be less robotic, to recognize humor, to banter, to look people in the eye, to not have a meltdown when criticized, etc.
Al Gore would make a good student body president there.
