Every 10 years, states redraw the boundaries of their congressional districts to reflect new population counts from the census. The Democratically controlled Nevada legislature drew the state’s new congressional map that Democratic Gov. Steve Sisolak signed into law in November 2021.
The new map unpacks the Democratic stronghold of the Las Vegas-based 1st District to make the other two southern districts — which have been highly competitive in recent years — more favorable to Democrats. However, the move also increases the chances that Democrats could potentially lose all three districts, including the 1st District, in a strong year for Republicans. The northern 2nd District continues to lean Republican.

How the new map shifts voting power by demographic
Nevada will continue to have four House seats. Under its new map, there will now be one district where White voters are the majority, rather than two. No group has a majority in the other three districts.
