You make a good point that communication was supposed to be his greatest strength.
He probably really uses communication as the metric to evaluate himself, if he really ever does any sort of self-evaluation, which is highly doubtful. He doesn’t seem to have any other standard by which he thinks he can be measured.
The only people left supporting him are either incredibly gullible, incredibly stupid or true leftists who really do believe he is their Messiah. It must be interesting to be one of those people in his inner circle who have their own reputations now attached to this complete and utter poser who is now, as you pointed out a failure at the one thing he was supposed to be good at even with the teleprompter and all the additional aid it gives him.
I think you have gotten to the very core of what Barak Obama actually believes is his single strength, his claim to fame. The Midterm election was Kryptonite to his verbal powers - his mellifluous words no longer have the effect they've alway had with audiences.
Political beliefs aside, Frank Marshall Davis aside, Bill Ayers and Bernardine Dohrn aside, “Reverand” Wright aside, George Soros aside, Stanley Dunham aside, Malcoln X aside, Barak Obama Sr. aside, Pakistani connections aside, terrorist propagandist Edward Said aside...Obama was boosted to where he is not only on how he looks, but more importantly how he sounds when he speaks.
This must have become apparent to him even as a child. He also learned verbal delivery skills. He looked just enough like a Black Man and talked just enough like a far left White Man, a combination that handlers back as far as Hawaii and Los Angeles, and then in New York City and Chicago, such as Bill Ayers the others of the violent radical Marxist Left found irresistible as an image they loved and could successfully sell as a facade for furthering their agenda.
How he speaks has been his cherished key to advancement. The election was kryptonite to that ability. The speaking doesn't work for him any more.
Once Obama fully realizes that the cat is out of the bag and that he will never, ever get back adulation about his speaking, he's truly finished.
All that will be left will be spite.
