North Carolina's political maps are expected to give Republicans majorities in the state legislature, and the U.S. House of Representatives delegation, even if Democrats win a majority of the statewide vote.

Lawyers representing state legislative leaders were in court Thursday in Raleigh, arguing to throw out an anti-gerrymandering lawsuit that targets the state’s new political districts.

The lawsuit argues that the state constitution guarantees the right to fair elections, and it says the new districts violate that promise. The Republican-led legislature argues that no such right exists, since it’s impossible to define what “fair” means.
