Alani Bankhead’s Montana Senate campaign is facing fresh doubts after a major PAC that spent millions backing her said it no longer sees a viable path to victory and is shifting its money out of the state. Bankhead won the Democratic primary and will stay in the race, even as some Democrats have pushed for a different strategy and the general election is shaping up as a three-way contest against Republican Kurt Alme and independent Seth Bodnar. Recent reports also say outside PAC spending has been heavy in the race, with Bankhead trailing in at least one new poll.
