On Thursday the Florida Supreme Court declined to hear a challenge to Gov. Ron DeSantis’ Congressional map which heavily favors Republicans, meaning the map is likely to stay in place for November’s midterms.

The decision means that Florida’s 1st District Court of Appeal will have the final say on the map. That court previously threw out a circuit court decision to redraw the map.

The Hill reports:

The state Supreme Court’s announcement came in response to a lawsuit filed by several outside groups alleging that the map approved by the state legislature violated the state’s Fair Districts amendments by diminishing the ability of Black voters to elect a representative of their choice.

The lawsuit focused on the redrawn 5th Congressional District, which is currently represented by Rep. Al Lawson (D). It argues that under the new map, Black voters will face a harder time electing a congressman of their choice, even though nearly half of the district’s residents are Black.

With the new map, Republicans are poised to gain four new GOP-leaning seats, meaning that 20 of the state’s 28 districts favor Republicans.

The GOP-controlled state legislature passed a different set of maps earlier this year, but DeSantis vetoed them and instead introduced his own maps. The legislature eventually signed off on those lines, infuriating Democrats, who have accused the governor of mounting a political power grab.

DeSantis has defended the new congressional map, calling it “race-neutral.”
