At then end of his very detailed and sourced (linked) article, Ed Lasky correctly says these constant and very pointed insults directed to all Americans need to be circulated (campaign ads) because this side of Obama (it’s every side of Obama) needs to be put in front of the voters (his state media has yawned and suppressed it).
I think most people know that Obama is an anti-American Muslim immigrant (and is basing their vote on that already); there is a dwindling number (though still enough to swing the election) that can be persuaded to vote against him.
The disturbing part is the large group that knows these things about him and still support him; they (like him) are enemies of our way of life.
