The Senate races in Arizona and Nevada remain undecided, with Democrats currently holding a narrow advantage.

In the western states of Arizona and Nevada, the U.S. Senate races are still undecided three days after Election Day on Nov. 5.

In the upcoming election, Democrats have a slight advantage in both races, giving hope to Chuck Schumer that his incoming minority may not decrease further. However, Republicans have already flipped four Senate seats and will begin the new year with a majority.

As of Friday morning, Sen. Jacky Rosen, D-Nev., has a lead of over 17,500 votes and 1.2 percentage points over her Republican opponent, Ret. Army Capt. Sam Brown. However, with tens of thousands of ballots still outstanding, the Associated Press has declared the race too close to call. The deadline for mail-in ballots to be counted in Nevada is Saturday.

Nearly 96% of Nevada precincts have reported their results, with Rosen leading Brown by 17,548 votes, or 2.26%.

"The Brown campaign stated on Thursday that there are still tens of thousands of uncounted ballots in the U.S. Senate race, with the candidates separated by less than one percent. Additionally, thousands of ballots need to be cured. Sam Brown is committed to ensuring every legally cast, valid vote is counted."

On Wednesday, Rosen stated, "We are optimistic about the outcomes, but there are still thousands of votes left to tally. Our democracy requires patience, and I am confident that we will ultimately prevail as more ballots are counted."

In neighboring Arizona, only 76.05% of precincts are reporting. Democratic Rep. Ruben Gallego, a Marine, currently leads Republican Kari Lake, a former TV news anchor, by more than 43,000 votes. The winner of this contest will succeed retiring Sen. Kyrsten Sinema, an independent who formerly was a Democrat. She left the party after clashing with its far-left element and decided against running for re-election as an independent when it became clear there was no path for her to do so.

The Arizona election results are being released gradually due to the state's vote counting process and the intricacy of this year's ballot. The most significant delays were anticipated in Maricopa County, the largest county in the state.

"Since 2006, Maricopa County has not had a two-page ballot, but this year it does, with races on both sides of those pages. There are four different sides of contests, with an average of seventy-nine contests. As a result, it is expected that it will take people a little longer to complete their ballots."

The GOP-supported state law, which aims to enhance ballot verification, may result in delays, according to officials.

Before delivering the green envelope ballots to the elections center for signature verification and vote counting, all such ballots must first be hand counted. This is in accordance with the law, which mandates that poll workers wait until the polls close before beginning the counting process.

If a voter's ballot contains an error, the election office allows five days for correction. However, election workers estimate that it could take up to two weeks to cure and count each ballot.

Before being counted, mail ballots must be scanned, sorted, and signature-verified. Additionally, voters have the option to return mail ballots at any time prior to polls closing on Election Day.

"The most crucial task you can undertake in the upcoming days is assisting [Turning Point Action] in verifying these ballots and ensuring that every vote is counted accurately in Arizona," Lake stated on X on Thursday.

Officials are still counting early votes in Arizona, including nearly half a million in Maricopa County. As a result, the race remains too early to call, with hundreds of thousands of ballots left to count.
