“the Florida Legislature finally caved to DeSantis’s wishes and passed one of his proposed congressional maps — the last major piece in the national redistricting puzzle. And befitting DeSantis’s national reputation (and ambitions), it is a dream map for partisan Republicans, single-handedly adding four new Republicans to the U.S. House of Representatives. But while DeSantis’s uncompromising insistence on maximizing Republican power may give him a nice story to tell if he runs for president, it could also be the map’s undoing in court.”
…
“This map will significantly shake up Florida’s congressional delegation, as it virtually guarantees that Democrats will lose three of their House seats in Florida”
…
“The map has an efficiency gap of R+20, which means Republicans would be expected to win 20 percent more seats under this map than under a hypothetical, perfectly fair map. Because Florida has 28 congressional seats, that translates to a 5.7-seat Republican bias — right on Texas’s heels for the “honor” of having the biggest bias of any state.”
…
“it didn’t have to be this way. Republicans in the Legislature initially passed maps that were significantly less biased. The state House passed a map in March that would have created 15 seats that were R+5 or redder and had an R+13 efficiency gap (though according to the inventors of efficiency gap, that would still qualify as gerrymandered). And in January, the state Senate passed a map that was close enough to fair (an efficiency gap of only R+6) that even most Democratic senators voted for it.
But DeSantis pledged to veto them both, insisting that only one of his uber-aggressive proposals would do.”
