"Brown, a longtime member of the Congressional Black Caucus and Progressive Caucus, represents a district that courts have found has already been unconstitutionally gerrymandered, by drawing a snake-shaped district that packed in voters of color, making the surrounding districts more white and conservative. Brown has protested the new proposed version of her district, in part because it includes 18 prisons filled with people unable to cast a ballot.
Lawmakers are currently in the process of fix the voting maps, attempting to obey an order from the Florida Supreme Court that they not be drawn to benefit any particular political party. But some are resisting that mandate, arguing that it’s a violation of their First Amendment rights. Two Republican Party chairmen have sued the state, claiming the anti-gerrymandering law infringed on their right to free expression."
