New Mexico Lt. Gov. John Sanchez (R) is expected to formally announce his Senate bid Tuesday, sources close to Sanchez confirmed to Roll Call.
Sanchez, who lost a bid for governor in 2002, had been expected to run for the open seat. The Hotline first reported the news.
Sanchez will face former Rep. Heather Wilson and at least two others in the Republican primary. Wilson, who lost the 2008 Senate primary, reported having more than $280,000 in the bank at the end of the first quarter.
Democrats also have a high-profile primary race between Rep. Martin Heinrich and state Auditor Hector Balderas.
United We Dream protesters carry a mock coffin to the office of Sen. Ted Cruz, R-Texas, in the Dirksen Senate Office Building on Monday, July 21, 2014, to hold one of their "funeral services for the Republican Party" due to GOP positions on immigration. The immigration reform group visited several other Senate Republican offices to hold similar funeral services.
