Barrack Obama is a person.. He is a gentleman.  He is a statesman..  He is for the little guy.  He leaves office with a current approval rating of 55%.  During his tenure he was hardly ever below 50%.  He had a 70% approval rating incoming in 2008.   
Contrary to Mr Trump.  He is not a gentleman.  He is not a statesman.  He is not for the little guy.  He comes into the oval office with a 37% approval rating.  That is the lowest rating of any incoming president ever.  He has baggage,  lots of it.   Will he make it 4 years.  I have my doubts.   I hope not.
