CHARLESTON, W.Va. (AP) — The West Virginia Legislature has voted to reorganize the state electoral map into 100 separate legislative districts for the House of Delegates.

The Senate's 30-3 approval Friday follows January passage in the House, where its 100 members together represent 67 districts.

More densely populated areas have two, three, four or five delegates.

Supporters say it will make each lawmaker more responsive and accessible. Critics say the change would cement more incumbents in office.

The Republican-sponsored bill, which passed the House 72-25 with several Democratic votes, would have lawmakers represent about 18,000 constituents each after the 2020 Census, evenly dividing the state's nearly 1.8 million residents among them.
