Here's a surprise, and not a welcome one... according to The Fix:
New Mexico Democratic Sen. Jeff Bingaman is expected to announce his retirement today, according to a source close to the decision, a move that further complicates his party's efforts to hold their Senate majority in 2012....
His retirement, however, creates an open seat contest that both national parties will almost certainly target. Democrats should start the race with an edge, however, given President Obama's 15-point victory margin in the state in 2008.
This comes despite some fundraising activity recently, and a strong showing in a recent PPP poll. That same poll showed Democratic Reps. Martin Heinrich and Ben Ray Lujan beating several Republicans in the event of a Bingaman retirement, so Dems aren't behind the 8-ball here, but, if this rumor is true, it's one more plate Patty Murray and the DSCC will have to keep spinning.
UPDATE: Inevitably, we turn to names of potential candidates. In addition to the obvious Heinrich and Lujan, Dave Catanese also cites youngish state Auditor Hector Balderas as a possibility (Balderas issued a statement already, but just to praise Bingaman). Also for the Dems, he reports that ex-LG and 2010 gubernatorial loser Diane Denish is "fully exploring the race" (and given her gubernatorial performance, hopefully those explorations will lead nowhere), as is state USDA Director Terry Brunner. On the GOP side, Rep. Steve Pearce says he'll "take a serious look" at the race.
ANOTHER UPDATE: Dave Weigel gets some confirmation from ex-Gov. Gary Johnson (the only GOPer to outpoll Heinrich and Lujan according to PPP) that he's still sticking with the presidential race and not switching to Senate.
