Benefits:
Logical reasoning.
Honesty.
Attention to detail.
Problems with that:
People are not logical. A politician isn't governing processes and data. A politician is governing people. They don't want to hear logic. They want to hear what will make them happy. They don't even want to hear what will work, if it is not what will make them happy.
Honesty. See logic. For all we scream we wish our pols would just tell us the truth, an honest statesman would probably start World War III.
Attention to detail would be nice. It might balance the budget and such, and we really need that. But a President is one person, and things are flying at you fast and thick. I think the executive function issues (especially trouble changing tasks and multitasking) would be bigger negatives than the attention to detail would be a positive.
Bottom line?? Save yourself a massive meltdown for absolutely nothing. Don't try to be the first Aspie President.
Now, being a presidential advisor might be a different story alltogether...
...if you could find a politician that would actually listen to reason.
