And, as FiveThirtyEight analyst Geoffrey Skelley has argued, Republicans might use their line-drawing power to pressure once-reliable Democratic candidates out of the House. Rep. Tim Ryan (D-Ohio) is mounting a Senate campaign, possibly in part because state-level Republicans seem poised to redraw his Youngstown-area district. Similarly, Rep. Charlie Crist (D-Fla.), once the state’s Republican governor, is seeking his old job, now as a Democrat, perhaps to avoid reelection in a newly drawn, increasingly competitive St. Petersburg seat. Rep. Filemon Vela — a Democrat who would have faced reelection in heavily Latino, red-trending Texas — announced his retirement before even seeing how Republicans would redraw his district. Put simply, the GOP doesn’t have to gain any political ground to win the House. It could take back the majority just by drawing district lines anew.
