"The Success Of A Con Man Augments His Panic"

This is quoted from memory from Rand. For each increment that Obama is to the left of what he is pretended to be, he is that much more of a fraud. He is under that much more of a panicky stress. For an admitted dope user, he will be that much more likely to use more and worse dope, for each increment as above.
The deceiver is destroyed by his fears of being found out; he breaks down. He breaks down the faster the further out from truth his deception runs. All of this hugely intensified by the scale of the attention on the one deceiver, who has all the world looking at him, and many may interpret what they see as a dope user.
