HELENA, Mont. (AP) — It didn't take long for the fallout to begin after Gov. Steve Bullock announced he was going to seek the Democratic nomination in Montana's U.S. Senate race.

Cora Neumann of Bozeman raised $650,000 during her five-month campaign but withdrew from the race on Monday.

So did physicist and mathematician Mike Knoles of Bozeman and Helena Mayor Wilmot Collins.

Neumann and Collins say they are endorsing Bullock. Knoles says the race is too important to let his ego dictate decisions and that Sen. Steve Daines "must go."

The Green Party qualified for the ballot on Friday and now has candidates for governor, U.S. Senate and U.S. House.
