He's frequently misunderestimated.

If the speculative 'diagnosis' offered in the video was correct, you'd expect him to show more pronounced issues in 2011 than the earlier video shown. Here's an interview on GMA for comparison:

Moving this video to carneval's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.

I wonder if this has to do more with a grasp of the issue vs unknowns. For instance, a governor has no real sense of nukes personally. Education, justice are all things one can have a more hands on grasp on at any level of government. Perhaps, though, it is just age. Hard to say. Nice video @carneval, I knew he wasn't a bat crazy governor when he was here, perhaps this really is an insight into a mind that is slowing drifting away.

Like Chomsky said it's a very careful act. He's a smart guy.

Maybe, just maybe, he actually believed in what he was doing in Texas and was speaking from the heart.

And maybe, in the process of being groomed for president, he realized he couldn't actually make a difference and stopped caring.
