A number of stories here and here out of Virginia describing how a number of black legislators would benefit from newly redistricted lines and may vote for the legislation. 

Dels. Onzlee Ware (Roanoke) and Rosalyn R. Dance (Petersburg) told The
Washington Post on Wednesday that they are considering the plan, which
would create a new majority-black district in Southside but also
disperse black voting power in at least eight other districts.

The likely outcome would be to elect a sixth black senator but also
to diminish the overall power of Democrats in the now evenly split
Senate.

“Here’s an opportunity where I can actually have a great
impact on African Americans, yet at the same time, it doesn’t help the
entire Democratic Party,” Ware said. “Should I always have to forgo the
interests of black people for the good of the party? . . . I have a real dilemma on my hands right now.”

and Delegate Rosalyn Dance:

“I don’t like the process,” Dance said. “But the irony of ironies is,
it’s going to be hard for us [to vote against the plan] as African
Americans because they create a minority seat.”
