Political Wire: “Abby Livingston: “The 2021 map was drawn for incumbent protection in a wave year, which could also be the case next year if historical trends hold up. To pick up new seats, Republican voters will need to be pulled from safe Republican seats to redden currently Democratic districts.”
The math: “If Republicans go after three seats this way, the changes can probably be made with little fanfare and concentrate mostly on South Texas, which is trending toward the G.O.P. anyway. But if they go big — aiming for, say, five seats — the lines could make reelection much more difficult for Republican incumbents in Houston and Dallas.
