(NewsNation) — With 51.9% of the vote, NewsNation/Decision Desk HQ has called the race for Arizona’s District 1 seat in the U.S. House of Representatives in favor of David Schweikert. See the results of the U.S. House and U.S. Senate races across the country here.

Republican Rep. David Schweikert faced Democratic challenger Amish Shah in the election while seeking his eighth term representing a district that includes the key swing areas of Phoenix and Scottsdale. 

Schweikert narrowly won reelection in 2022 in the traditionally Republican district by less than 3,200 votes. 

Schweikert, who has established himself as a conservative lawmaker, has also become known for his passion for financial and tax issues. His policies remained popular with fellow Republicans as the economy remained at the top of voters’ minds around the U.S.

The Cook Political Report called Arizona-1 one of 25 toss-up races around the country that could help determine control of the U.S. House of Representatives.

Shah, a doctor and former Democratic lawmaker, advanced to Tuesday’s general election after defeating five primary challengers.

Shah has served five years in the Arizona House of Representatives. First elected in 2018, the emergency room physician became the state representative for the greater Phoenix area after redistricting took place in 2020. 

Shah became known as a proponent of bipartisan politics who broke from his Democratic colleagues on issues such as immigration. He prioritized securing the southern U.S. border, which remained a critical issue for Arizona voters throughout the lead to Tuesday’s election.

Heading into Tuesday’s election, all 435 seats in the House of Representatives were up for election. Republicans control the chamber with a narrow majority of 220 seats, while the Democrats occupy 212 with three vacancies.
