Former Michigan Secretary of State Terri Lynn Land (R) said Thursday she will not run against Sen. Debbie Stabenow (D) in 2012, leaving Republicans still in the hunt for a top challenger.

Land wrote on her Facebook page Thursday morning that she would not run for the Senate.

“At this time, I have decided not to be a candidate for the US Senate, but I will continue to support and be involved with conservative people who will lead our country to prosperity and protect our freedoms,” she wrote.

Land is the second Republican to take a pass on a bid against Stabenow this year. Former Rep. Pete Hoekstra (R-Mich.), who unsuccessfully ran for governor last year, announced last month that he would not pursue the seat.

Former Michigan Republican Party Chairman Saul Anuzis (R) has also been mentioned as a possible candidate, but a voice mail message left on his phone seeking comment was not immediately returned.

There’s also been speculation that one of the current members of the delegation might also run against Stabenow, although none of the Republican House Members has openly discussed a potential campaign.
