He's not organizing it or holding it, he's speaking at it. As your snippet says, it's hosted by the S.C. NAACP.

From the Charlotte Observer:

The democratic socialist U.S. senator from Vermont is one of two prospective presidential candidates taking part in Monday’s State House rally. U.S. Sen. Cory Booker, D-N.J., also will speak at the event.

Awkward!!

...there are less than 8,000 African Americans state-wide.

....about civil rights in America would relocate, in the midst of his civil rights activism, to one of the whitest states in the country instead of remaining in one of the most racially and religiously diverse states in the country.

his and his supporters' claim that he is some great civil rights hero who sacrificed so much for the cause because he protested and got arrested once when he was in college.

....maintain that he's a civil rights activist is puzzling.

I'll tell you one thing, John Lewis never did that.

For his sake, let's hope he does better this time.

that most blacks were poor and hanging around on street corners.

This would be good exposure for him and his campaign where he will meet some real world African Americans many of whom are doctors, lawyers, administrators, nurses, teachers, policemen, firefighters etc.

He may also be persuaded to not equate economic justice with social justice like he was prone to do.

Good for Bernie. Education is always good and it is never too late.

Great that he's speaking Monday! He's a national treasure.

It's time we lay these petty hatreds aside and focus on what matters.

I'm glad you're setting the hate aside and striving for unity.

Proud of your progress George.

I quit listening to BS early on, racism. The other is feminism.
