Obama’s intervention into the primary process is going to spark a much more surgical examination of his own presidential record.
As David Bromwich writes in American Breakdown: the Trump Years and How They Befell Us:
“Anyone who voted twice for Obama and was baffled twice by what followed–there must be millions of us–will feel that this president deserves a kind of criticism he has seldom received. Yet we are held back by an admonitory intuition. His predecessor was worse, and his successor most likely will also be worse.”
Bromwich wrote these words in 2015; all of what he describes, however, will start to shift the moment Obama steps back into the intra-prarty fray.
