Republican Andy Biggs easily defeated Democrat Talia Fuentes to take Arizona's Congressional District 5 seat Tuesday.
Biggs, who beat fellow Republican Christine Jones by just 27 votes after a recount in August's GOP primary, won with more than 80 percent of the vote.
In the other easy-win districts, Democrats Kyrsten Sinema, Ruben Gallego and Raul Grijalva won re-election, as did Republicans Paul Gosar, David Schweikert and Trent Franks.
A top member of the state Senate, Biggs succeeds Matt Salmon, who announced his retirement in February.
