More bad news for the national Democratic Party in retaining the U.S. Senate majority in 2012.

Senate Energy Chairman Jeff Bingaman, D-N.M., will announce on Saturday that he will not seek reelection, Democratic sources confirmed. The news was first reported by the Washington Post.

Bingaman, who was first elected in 1982, will become the fourth Democratic Caucus member and sixth incumbent to announce they will not seek reelection in 2012.  Sens. Joe Lieberman (ID-Conn.), Kent Conrad (D-N.D.), and Jim Webb (D-Va.) have previously announced they will not be running in 2012.

So, who might run?

Reps. Martin Heinrich and Ben Ray Lujan will almost certainly be mentioned on the Democratic side as might that of former Lt. Gov. Diane Denish.

Former Rep. Heather Wilson has been mentioned as a possible Republican candidate and sources close to Rep. Steve Pearce say he is looking seriously at running.

No matter if the Democrats have a large majority of registered voters in the state, they will need to expend far more resources in New Mexico than if Jeff Bingaman had decided to run for re-election. President Obama remains popular in the state, according to the latest polls, but a mistake by a Democratic nominee for Senate could hurt him.

The White House and Senate Majority leader Harry Reid cannot be too pleased.
