I have to agree. His manifesto was full of typos and grammar problems. He seemed very low IQ. I saw on DU how they were praising his intelligence. Obvious affirmative action thinking going on there.
There have been assertions about how tests used to measure various things from job suitability to intelligence are skewed by inherent racism in those tests. I don't believe that is primarily the case.
But if there were a test that measured "Media IQ" as imparted on a person by the media and liberalism, he would have a very high IQ by that standard, as twisted as it is.
His very ability to interpret his surroundings was indelibly impressed upon him by watching television like CNN, ABC, CBS and NBC, reading papers such as the NYT, Boston Globe and Washington Post and magazines such as Time and Newsweek, and by drinking in the elixir of liberalism that they have been brewing up since Woodrow Wilson was president.
I found the manifesto to be manifestly creepy in that way, the celebrity worship and cult of personality that it was rife with. There are a lot of people like him who are simply saturated with that.
And many of them want to go much further down the path of "Change" as exemplified by the radicals now in charge of the Democratic party.
