Both parties have used gerrymandering in their favor, but Republicans have made more gains through gerrymandering in the past decade. By targeting key state legislative races in 2010, Republicans gained 675 legislative seats, and gained control of 12 state legislatures. The result: Republicans got to redraw four times as many congressional districts as Democrats. If we don’t change the law, both parties will try to do it again in 2020: the Republicans with REDMAP 2020, and the Democrats with Advantage 2020.
If we keep the current system and the Democrats try to take partisan advantage, there could be payback. Fair Districts PA would rather see redistricting reform that would put partisanship in the past.
