The New Mexico Supreme Court is scheduled to hear oral arguments Monday in a legal challenge to a congressional map that divvies up a politically conservative region of the state.

It’s one of several court battles in states from Kentucky to Utah regarding U.S. House districts enacted by state legislatures and alleged constitutional violations.

The Republican Party and several other plaintiffs have accused Democratic lawmakers in New Mexico of breaking up the southeastern corner of the state — an oil producing region and Republican stronghold — into three districts “for raw political gain.”

The case holds implications for the 2nd Congressional District where Democrat Gabe Vasquez in November ousted incumbent U.S. Rep. Yvette Herrell. The majority-Hispanic district currently stretches from the U.S. border with Mexico across desert oilfields and portions of Albuquerque.

Clovis-based District Judge Fred Van Soelen in April cleared the way for Republicans to challenge the new congressional map, while barring immediate changes that might have disrupted the 2022 midterm election.

Democratic Gov. Michelle Lujan Grisham and leading Democratic legislators have asked the Supreme Court to intervene and preserve their redistricting plan. They say new boundaries to the state’s three congressional districts were vetted appropriately through the political process to ensure more competitive districts that reflect population shifts, with deference to Native American communities.
