Steve Daines was born in Van Nuys, Ca. and was raised in Bozeman, Mont., where he still lives. Daines graduated from Montana State University in Bozeman with a bachelor's degree in chemical engineering.
He spent more than a decade working for Procter and Gamble, splitting work between the United States and international assignments.
Daines is a vice president at RightNow Techologies, a Bozeman-based software company, where he has worked since 2000.
Daines and his wife, Cindy, have four children.
Steve Daines, a Bozeman businessman who has never held political office, easily won the June 2012 Republican primary for Montana's sole U.S. House seat.
He has been considered the GOP front-runner since the start of the election cycle.
Daines originally planned to run for U.S. Senate against first-term Democratic incumbent Sen. Jon Tester. He dropped that bid in early 2011 when U.S. Rep. Denny Rehberg announced his candidacy for the Senate.
Daines instead switched his campaign to succeed Rehberg. Republicans have held the state's congressional seat since 1997.
With little competition in the primary, Daines has stockpiled far more cash than his Democratic 2012 opponent, state Sen. Kim Gillan.
Daines has campaigned against President Barack Obama's policies, and he has called for reductions in federal spending and taxes.
Daines opposes the 2010 health care reform law. However, he has suggested that some provisions, such as the one preventing insurers from denying coverage for pre-existing conditions, could be kept if modified.
He is opposed to abortion and gay marriage.
In 2008, he was selected by Republican gubernatorial candidate Roy Brown to run as lieutenant governor. The pair lost handily to the incumbents, Gov. Brian Schweitzer and Lt. Gov. John Bohlinger.
Daines was a delegate for Ronald Reagan at the 1984 GOP convention.
