Conservative groups are pouring millions into Montana’s Senate primary

Millions of dollars are flowing into Montana’s US Senate race before voters go to the polls on Tuesday — and that’s just for the Republican primary.

GOP candidates and conservative outside groups have already poured about $5.7 million into the primary for Montana’s US Senate race on Tuesday. That’s about $5.60 per resident and about $8 per registered voter in the state, which has a population of about 1 million. Even in increasingly expensive general elections, this level of spending in a primary is something new.

“We really haven’t seen this level of spending in a primary in any of the cycles I’m aware of,” University of Montana journalism professor Lee Banville said.
