Disagree w you re: corpse man. Obama hates the USA, the military, & Marines in particular. “Corpse man” was his in-your-face diss to a group of Americans he particularly despises. (Fits right in w his snarky, immature, middle-finger mentality. He is a petty, nasty man; Biden wd be a vast improvement.)
You could be right. I agree that he shows signs of having a petty, nasty, juvenile temperament.
And he obviously believes his own press.
Personally, I still attribute it to an utter ignorance of our military, combined with an overrated intellect that doesn’t bother to check out the correct pronunciation of the word, and a lack of any real need to do so, since the same media that crucified Bush for such gaffes gives Obama a pass on all of them.
But, I could be wrong. You could be right about that.
