It's true. State Auditor Hector Balderas has filed a statement of candidacy with the Federal Election Commission for a Senate race, someone familiar with the campaign told me. He's expected to announce his candidacy early next week.
Balderas will face U.S. Rep, Martin Heinrich in the Democratic primary in June 2012.
Albuquerque community activist Andres Valdez also has said he'll run for the seat currently belong to U.S. Sen. Jeff Bingaman who is retiring.
