Barack Obama's blunt message to Black men who may not vote for Kamala Harris sparks debate on how Democrats can recover their support.

Mr. Obama didn’t argue policy, performance or better ideas. He asserted that Black men owe Ms. Harris their vote. Otherwise, they are women haters who are failing in their duty. The reaction to Mr. Obama’s diatribe has been negative in a way that would have been unthinkable 10 years ago.
