WATCH: Key takeaways from Election Day 2022

WASHINGTON (AP) — Republicans were closing in Wednesday on a narrow House majority while control of the Senate hinged on tight Arizona, Nevada and Georgia races in a midterm election that defied expectations of sweeping conservative victories driven by frustration over inflation and President Joe Biden’s leadership.

John Fetterman’s success in flipping Pennsylvania’s Republican-controlled Senate seat lifted Democratic hopes of maintaining control of the chamber. The Georgia Senate race between Democratic Sen. Raphael Warnock and Republican Herschel Walker was headed to a Dec. 6 runoff. Republicans found a bright spot in Wisconsin, where Sen. Ron Johnson’s victory raised the stakes of races where results were unclear and vote counting continued.

In the House, Democrats kept seats in districts from Virginia to Kansas to Rhode Island, while many in states like New York and California had not been called. But Republicans notched several important victories in their bid to flip the five seats needed to reclaim the House majority. In a particularly symbolic victory, the GOP toppled House Democratic campaign chief Sean Patrick Maloney of New York.

The race for control of Congress will determine the future of Biden’s agenda and serve as a referendum on his administration as the nation reels from record-high inflation and concerns over the direction of the country. A Republican House majority would likely trigger a spate of investigations into Biden and his family, while a GOP Senate takeover would hobble the president’s ability to make judicial appointments.
