HELENA, Mont. -

The campaign for control of the Montana Legislature is underway with 125 House and Senate seats up for grabs in November's general election.

State Sen. Ed Walker is the GOP legislative campaign committee director. He said Wednesday he expects Republicans to unite for the general election despite harsh primary fights between conservative and moderate GOP candidates.

Incumbents mostly held on against primary challengers in Tuesday's elections, though some races came down to the wire. In one, conservative Sen. Scott Boulanger of Darby lost in a squeaker to challenger Patrick Connell in a Senate race marked by mailers attacking both candidates.

The Secretary of State's office estimated more than 219,000 people voted in Tuesday's primary, with more than a dozen precincts yet to fully report.
