Former Michigan Secretary of State and current Michigan Republican National Committeewoman Terri Lynn Land is running for Senate.
Land launches run for Levin's Senate seat
Land was elected SOS in 2002 with 55% and reelected in 2006 with 56%. She has had success winning statewide elections, though neither were against top opponents.
She is generally considered a mainstream conservative. However, as SOS she did not have to take positions on many specific issues, so there is much that is yet to be known about her views.
No other Republicans have entered the race, though a few are still considering it. Congressman Gary Peters is expected to be the democrat nominee.
