SANTA FE,Ov Finance N.M. (AP) — The top-ranked Republican in the New Mexico Senate won’t seek reelection this year as his party reckons with the first election since a redistricting plan from Democrats merged two GOP-led districts.

Senate Republican leader Greg Baca of Belen said his decision to leave the Senate by year’s end was informed by conversations with his family, prayer and attention to new political boundaries adopted by the Democrat-led Legislature in 2021.

“Careful observers of the progressive plan to pit two Hispanic Republicans against each other through redistricting may have seen this coming,” said Baca in a statement, while endorsing Republican state Sen. Josh Sanchez in the merged district. “In short, I refuse to allow the radical left to pit brother against brother.”

State legislative candidates raced against a Tuesday-evening deadline to submit signature petitions that can qualify them for the state’s June 4 primary and November general election.

Democrats outnumber Republicans nearly 2-1 in the state Senate, amid a wave of retirement announcements that could tilt the partisan balance next year. The entire Legislature is up for election in November.

In drawing new Senate districts, the Legislature embraced recommendations from Native American communities for shoring up Indigenous voting blocs in the northwest of the state. But Republicans at the same time bristled at provisions that merged two Republican-held districts.

The Legislature’s annual session adjourned in mid-February with approval of several public safety initiatives and an annual budget plan that slows down a spending spree linked to an oil production bonanza in the Permian Basin that overlaps southeastern New Mexico and portions of Texas.

Separately on Tuesday, four state House Republican legislators from southeastern New Mexico and Farmington urged the state land commissioner to reverse course on her decision to withhold some lease sales for oil and gas development until the Legislature agrees to raise royalty rates in premium tracts from 20% to 25%.

A letter to Land Commissioner Stephanie Garcia Richard warns of possible unintended consequences including job losses and reduced government income if petroleum producers redirect investments from New Mexico to other oil fields. It was signed by Republican state Reps. Jim Townsend of Artesia, Larry Scott of Hobbs, Rod Montoya of Farmington and Jared Hembree of Roswell.

State Land Commissioner Stephanie Garcia Richard said the state will forgo a trove of income and investment returns over the lifetime of future leases if royalties stay capped at 20%. In New Mexico, royalty payments from oil and gas development on state trust land are deposited in a multibillion-dollar investment trust that benefits public schools, universities and hospitals.

The accountability and budget office of the Legislature says a 25% royalty rate cap would increase annual revenues by $50 million to $75 million.
