On October 13-15, a three-judge U.S. District Court heard arguments in David Harris v McCrory, m.d., 1:13cv-949. The issue is whether North Carolina’s U.S. House districts are valid. See this story. There are also lawsuits pending in North Carolina state court and federal court over the state’s legislative district boundaries. The judges are: William Osteen, a Bush Jr. appointee; Roger Gregory, a Clinton appointee; and Max Cogburn, an Obama appointee.

If the districts must be redrawn, that may affect the date of the 2016 primary, which is now set for March 15. In 2004, North Carolina also had late redistricting, and the primary was postponed from May 4 to July 20; there was no presidential primary that year. Also, in Texas in 2012, late redistricting forced the primary to move from March 6 to May 29. When primaries are postponed, independent candidate petition deadlines are changed to later dates.

Redistricting lawsuit decisions are expected fairly soon in Alabama, Florida, Texas, and Virginia.
