The House voted along party lines for a map that redraws the chamber’s 120 districts, which are based on population changes recorded in the 2020 census. The new boundaries — if they’re enacted and if they withstand litigation — should keep the GOP in a good position to retain the majority it’s held since 2011. Democrats and outside analysts predict Republicans could win at least 10 of those seats — two more than they currently hold — if the map is used.
