The GOP flipped four seats. Three were open seats: Missouri (Jay Ashcroft), Montana (Corey Stapleton), and Oregon (Dennis Richardson). The Oregon contest was the most surprising, with the GOP winning their first statewide office in more than a decade.
The other seat the GOP flipped was in West Virginia, where Republican Andrew "Mac" Warner ousted incumbent Democrat Natalie Tennant.
The Democrats did flip one seat, as Maggie Toulouse Oliver won a Republican-held seat in New Mexico.
The Democrats also held on to seats in North Carolina, where Elaine Marshall was re-elected, and Vermont, where incumbent Jim Condos faced no major-party opposition.
And the Republicans held the office in Washington state, as incumbent Kim Wyman won another term.
