Democrats who run populous states are considering redistricting, but some of them face a hurdle: Their parties don’t have control over drawing legislative maps.

Democrats have vowed to “fight fire with fire” since the GOP moved to add five red seats in Texas, but they face many barriers.

Democratic lawmakers from Texas say they’re considering their options amid a report they could return to the state as soon as this weekend, a move that may end a standoff in which more than 50 state representatives left in a bid to block controversial new congressional maps backed by President Donald Trump.
