HELENA, Mont. -

The field for Montana's June 3 primary elections is taking shape as candidates file their last-minute paperwork with the Secretary of State's office.

Democratic and Republican primaries will be held to choose party nominees for the state's open U.S. Senate and House seats.

Multiple candidates from both parties filed to run for those two seats before Monday evening's deadline.

Democrats say they have at least one candidate for each of the 125 state House and Senate seats up for election for the first time in recent memory.

Republicans now control both chambers.

There also will be a competitive race for Montana Supreme Court, with Justice Jim Rice defending his seat against challenger W. David Herbert.

Three Republicans are competing to be the nominee for an open Public Service Commission seat.
