Former state GOP chair becomes fifth Republican in 2020 U.S. House race

Lamm said the upcoming election is a battle over a future “defined by socialism or American exceptionalism,” and that as a member of Congress she would “stand with President Trump to protect this country and our Montana way of life.”

Lamm, who just completed a two-year stint as chair of the state Republican Party, is an attorney from Livingston. She was elected as a state representative in 2014, but lost the seat in 2016 to Democrat Laurie Bishop.
