NYT:

Mr. Reives is one of a growing number of Black elected officials across the country — ranging from members of Congress to county commissioners — who have been drawn out of their districts, placed in newly competitive districts or bundled into new districts where they must vie against incumbents from their own party.

Almost all of the affected lawmakers are Democrats, and most of the mapmakers are white Republicans. The G.O.P. is currently seeking to widen its advantage in states including North Carolina, Ohio, Georgia and Texas, and because partisan gerrymandering has long been difficult to disentangle from racial gerrymandering, proving the motive can be troublesome.

But the effect remains the same: less political power for communities of color.

The pattern has grown more pronounced during this year’s redistricting cycle, the first since the Supreme Court struck down the heart of the Voting Rights Act in 2013 and allowed jurisdictions with a history of voting discrimination to pass election laws and draw political maps without approval from the Justice Department….

Across the country, the precise number of elected officials of color who have had their districts changed in such ways is difficult to pinpoint. The New York Times identified more than two dozen of these officials, but there are probably significantly more in county and municipal districts. And whose seats are vulnerable or safe depends on a variety of factors, including the political environment at the time of elections.

But the number of Black legislators being drawn out of their districts outpaces that of recent redistricting cycles, when voting rights groups frequently found themselves in court trying to preserve existing majority-minority districts as often as they sought to create new ones.

“Without a doubt it’s worse than it was in any recent decade,” said Leah Aden, a deputy director of litigation at the NAACP Legal Defense and Educational Fund Inc. “We have so much to contend with and it’s all happening very quickly.”
