HARRISBURG (AP) – There may be nothing more nerve-wracking for a member of Congress than redistricting, when the once-a-decade redrawing of district boundaries injects uncertainty into their political career. By the end of April, the U.S. Census Bureau is releasing the first numbers from the 2020 census. It includes the state population count that determines how many congressional seats and Electoral College votes each state gets. PA is expected to lose a district. That means there will be 17 districts for 18 incumbent U.S. House members from the Keystone State when next year’s elections roll around. If each of the 18 wants to run again, two of them will have to run against each other.
