More than two days after polls closed across the United States, control of both houses of Congress is still up for grabs, with many races not yet called.
The Senate picture is becoming clear. Republicans hold 49 seats and Democrats hold 48. The races in Arizona and Nevada have not been called, and Georgia is gearing up for a runoff.
In the House, Republicans are inching toward a narrow majority. But as of early Friday morning, there were still more than 10 undecided races in what the Cook Political Report designated as some of the most competitive districts. Many of the uncalled races were in western states, where Democrats are looking to flip Republican-held seats.
Here’s a closer look at where things stand on Thursday afternoon:
Arizona: Senator Mark Kelly, a Democrat and former astronaut who built a national profile as a gun safety advocate, is leading the Republican, Blake Masters, a political newcomer and venture capitalist.
Nevada: Senator Catherine Cortez Masto, a Democrat, is narrowly trailing Adam Laxalt, a Republican former Nevada attorney general, but Democrats and independent analysts say that they expect the ballots that have not yet been counted to favor Ms. Cortez Masto. Election officials in Las Vegas’s Clark County must wait for mail-in ballots postmarked as late as Tuesday, meaning a final count will probably not be announced until next week.
Georgia: The race between Senator Raphael Warnock, a Democrat, and Herschel Walker, a Republican and former football star, will continue into a December runoff after neither candidate cleared the 50 percent threshold to win outright.
