I have seen 1st hand this NPD. Liberals are definitely narcissistic whether they have this disorder or not. But the first on your list is THE achilles heel. Criticism by ridicule is what they loathe. Go ahead and mock a liberal for their beliefs and watch the fireworks. Alinsky's Rules pointed out that ridicule is a powerful weapon, not realizing that he was projecting his weakness on his supposed enemies.
And this is Obama's Achilles Heel. He has a paper thin skin and will explode if prodded hard enough and often enough. His management style is dictatorial and his personal belief that he has ALL the answers and only he knows what is best will cause him to implode/explode if prodded often and hard enough.
