Tight races in New Mexico, Iowa

As Grisham nears the end of her second term as New Mexico governor, candidates contend to replace her in a packed primary.

Haaland, who served on President Joe Biden’s Cabinet, is expected to win the Democratic nomination, according to The New York Times.

In the more crowded Republican primary, Hull is favored to edge out the other two candidates.

Incumbent Democratic Rep. Melanie Stansbury of New Mexico’s 1st Congressional District is also expected to face opposition in November from Republican Ndidiamaka Okpareke. Both candidates are running unopposed for their respective primaries.

In Iowa, Gov. Kim Reynolds is finishing up a ten-year run, giving Democrats their first open-shot opportunity to reclaim the governor’s office since Gov. Chet Culver left office in 2011.

Iowa Gov. Kim Reynolds speaks during a news conference, Jan. 31, 2024, at the Statehouse in Des Moines, Iowa. Iowa has been the only state in the U.S. to explicitly mandate that state, county and local decision-making bodies are balanced by gender. That will end when Gov. Reynolds signs a bill that aligns with a broader abrogation of gender- and race-conscious policies across the country. | Charlie Neibergall, Associated Press

On the Democratic side, five candidates are competing for the nomination with Reilly Neill, a former state representative, leading the pack.

Rep. Zinke’s decision not to pursue reelection in the House has made the seat much more competitive.

Four Republicans and four Democrats seek Zinke’s seat, with veteran and talk show host Aaron Flint leading in the GOP polls. Flint has also received endorsements from Zinke and Trump.

The outcomes of these midterm elections will shape whether Republicans can maintain a majority in House and Senate in November.
