Democratic U.S. Rep. Ben Ray Lujan has won a fourth term with a victory over Republican Jeff Byrd.
Lujan, vice chairman of the Congressional Hispanic Caucus, has said making New Mexico more competitive will be at the top of his list when he returns to Washington.
The congressman has also called for the National Nuclear Security Administration to be restructured to better balance defense programs with other research. His district includes Los Alamos National Laboratory.
Byrd had criticized Lujan, saying promises he made to northern New Mexico residents have gone unfilled.
In southern New Mexico, Republican U.S. Rep. Steve Pearce fended off a feisty attack from Democrat Roxanne "Rocky" Lara to keep his seat.
In the 1st District, Democrat Michelle Lujan Grisham has an early lead over Republican challenger Mike Frese.
