Montana Gov. Steve Bullock says the state's economy is strong, as the Democrat makes his case for re-election.

The economy is expected to play a central role in this year's governor's race. Republican challenger Greg Gianforte has made Montana's low wages his campaign's central theme.

During a news conference in the Capitol, Bullock cited the state's 4 percent unemployment rate as a key indicator of Montana's economy. The state's jobless rate is one point below the national rate.

The governor's report, which was not made available prior to his briefing, was compiled by his economic advisers. The report is a compilation of mostly glowing information about the economy, including rising wages and the state's business climate.
