Steve, of course Obama in his book 'The audacity of hope' did not write nor imply that he was a demigod. On the contrary, he was very humble and inspirational and full of spirituality about America being a great country (they sounded like the words of Donald Trump) and how to extend bipartisanship and avoid divisiveness. He did not write he was a demigod, but the vibrations of the book were there, as if a very spiritual man had written it, as if this grandiose figure of a politician was sent by God and the high creatures of the causal world to save humanity.
But in reality he showed some (a lot?) of hypocrisy. He couldn't stand Trump. It became personal, maybe because of the episode you cited, the birth certificate. It is very well known the meeting where he ridiculed Trump. 'I am a President, he will never become like me'. A spiritual being would have been passionate and understanding toward an inferior being like Trump, not ridicule him in public. This is not exactly an attitude I expected after reading the book. I also remember well Obama's expression when Ben Carson harshly criticized him in a public speech, they were together. Maybe he didn't expect it but Obama's face became very serious and hurt and almost hateful. He may have thought: 'He dared criticize me! The best politician since Abraham Lincoln'! I remained stunned by that.
Also, his presidency in external affairs was a downright disaster, with one notable exception, I'll admit, the killing of Bin Laden, which gained him a second mandate. I think a demon suggested to him how to organize the killing so that he could be re-elected and keep ruining the world.
Fuhrer Trump, always in external affairs, was far, far better.
So, Trump is a liar, but a poor liar. Obama has been a more sinister and devious liar. The former (Trump) is a dumbass. The latter (Obama) is an ominous soul, deceiving America and the world.
If I were a real demigod, I would reset all history and have these two candidates (The fuhrer and the comrade) deleted.
America deserves a real president.
