Langevin will face Republican Michael Riley, who won a four-way primary against Kara Russo, Donald Robbio and Michael Gardiner to secure his party’s nomination.
Riley, a Narragansett resident, stressed his experience as an investment banker during his campaign and said he favors cutting government spending and revising the tax code to spur the economy.
‘‘I'm on a mission,’’ Riley said. ‘‘My idea is to take action. What we have is a guy (Langevin) who has been here for 12 years and hasn’t produced a lot.’’
The 2nd District includes the southern and western bulk of the state.
