I believe we've seen the real Obama these last ten years and we're better for it.  One thing I'll not forget from the 2008 campaign. Both John McCain and Hilary Clinton came out against a gasoline tax. Obama took the less popular but more correct stand in favor of it. And still got himself nominated and elected. Obama has always displayed admirable self control and been the furthest thing from an "Angry Black Man" that many of his detractors attempted to paint him as.
More recently, Trump, the Republican nominees, Hilary AND Sanders maintained that the TPP was against American interests, which is not true. Obama continued to support it, taking the long view of what was good for this country.
Obama is the only American President who has grown up part of his life in an Islamic society (Indonesia) and I think this informed his development and will continue to in his post-Presidential years, for the better.
