For years, political parties in most states have avoided getting involved in primary races -- leaving the choice to voters. But in many places, those elections are looking different this year.

As property values rise, Montana is seeking to cut taxes for most properties but raise them for out-of-state homeowners.

Montana not only went enthusiastically for Trump for a third time, but took the last statewide seat held by a Democrat. Senator Jon Tester's defeat caps a years-long quest to erase purple from Montana's map.

Montana could help decide control of the U.S. Senate this cycle. With polls showing former Trump leading in the state, Tester will need voters who aren't sold on either party to hang on to his seat.

Jon Tester's three US Senate race wins have all come with razor thin margins, meaning third party candidates can tip races. Now a Libertarian candidate says he thinks Donald Trump is pressuring him to drop out.

Candidates in Montana’s U.S. Senate race are focused on veteran issues -- as former service members could help decide the election, and control of the Senate.

Republican Tim Sheehy won his party’s nomination to run for Montana’s U.S. Senate seat on Tuesday.

Republican Gov. Greg Gianforte is being challenged from the right during a primary election this year. His opponent says the incumbent, who once body-slammed a reporter, isn’t conservative enough.

Tester is the last Democrat holding statewide office as Republicans have dominated recent elections in Montana. He's carved out an identity as a moderate and he hopes that will win him another term.

Sen. Jon Tester of Montana will have to walk a fine line as a Democrat running for re-election in a state where Donald Trump is popular. Will his strategy of appearing moderate work?
