Bozeman Republican “Steve Daines is expected to announce Saturday that he is challenging Democratic U.S. Sen. Jon Tester in 2012,” the Billings Gazette reports.
Daines, a businessman and the Republican nominee for lieutenant governor in 2008, was not available for comment.
The leading potential “Republican contender for the seat, U.S. Rep. Denny Rehberg, has not yet announced his plans for 2012.”
Tester “announced in June that he will be seeking a second Senate term.”
Update (2/3/2011): Daines “announced Thursday that he is abandoning his Montana Senate bid to instead run for the House,” Roll Call reports.
