The New York Times reports:
Gov. Steve Bullock of Montana is poised to reverse himself and run for the Senate, according to three Democratic officials, a decision that would hand the party a coveted recruit who could help reclaim a majority in the chamber.
After months of insisting he would not challenge Senator Steve Daines, Mr. Bullock, who ran for president last year, has told Democrats in the last week he is now inclined to run in what would immediately become one of the marquee Senate races of 2020.
Mr. Bullock has only a few days to finalize his decision: the filing deadline to run in Montana is Monday.
