You can't shit on Umar as a charlatan and ride for:

Obama
The DNC
The DLC
Hillary
Black Lives Matters
The Root
Very Smart Brothas.

Umar may very well be crooked (again, I got no opinion of him, really), but his appeal to working poor black folks is pretty understandable. And he ain't NOWHERE NEAR as corrupt or harmful to the black community as the above people.
But those folks are accepted by large chunks of middle class black folks unconditionally.
That's partly what I mean by class war...the outrage from a certain class of black folks only punches down.
