Sen. Jon Tester, a Democrat in a state that President Trump won by about 20 points, is vulnerable as he seeks a third term. Tester's opponent is Republican state auditor Matt Rosendale. Democrats have argued Rosendale is a developer from Maryland who dresses up as a Montana rancher. Rosendale's campaign focuses on his close ties to Trump and paints Tester as a liberal who is out of touch with his conservative state. The race for Montana's single House seat could also be competitive. Republican Rep. Greg Gianforte is up for his first full term after winning a highly publicized special election last year to replace Interior Secretary Ryan Zinke. Gianforte, who assaulted a reporter the night before his election victory, will face former state legislator Kathleen Williams (D).
