"After much deliberation, I have decided not to seek the U.S. House or Senate seats in 2014," Juneau states in a Facebook post. "I sincerely appreciate the outpouring of support and encouragement I have received from people all across Montana and the country. It has been very humbling to be considered for such a leadership role representing our great state; however, my decision not to run for Congress is the right one for me at this time."
A top Baucus staffer left his job at the end of last week in order to explore a bid. Other potential candidates include Montana Lt. Gov. John Walsh, state Supreme Court Justice Brian Morris and Montana state Sen. Kendall van Dyk.
On the GOP side, many expect Rep. Steve Daines (R-Mont.) to run.
