Florida Republicans are poised to adopt one of the nation’s most aggressive congressional maps, pressing forward with a proposal from Gov. Ron DeSantis that would most likely add four congressional districts for the party while eliminating three held by Democrats.
The map, which the Florida Senate approved by a party-line vote of 24 to 15 on Wednesday during a special session of the Legislature, was put forward by Mr. DeSantis after he vetoed a version approved in March by state legislators that would have added two Republican seats and subtracted one from the Democrats.
The new proposal would create 20 seats that favor Republicans and just eight that tilt toward Democrats, meaning that the G.O.P. would be likely to hold 71 percent of the seats. Former President Donald J. Trump carried Florida in 2020 with 51.2 percent of the vote.
