While the Republicans have secured at least 52 seats in the new Senate resulting from their candidates’ partisan conversion victories in Montana, Ohio, and West Virginia, three more races remain uncalled. Those are found in Arizona, Nevada, and Pennsylvania.

After polling consistently projected Arizona Rep. Ruben Gallego (D-Phoenix) running well ahead of former news anchor and 2022 Republican gubernatorial nominee Kari Lake for most of the general election campaign cycle, the race closed at the end.

The current totals, not final because approximately 1.04 million votes remain to be counted find Rep. Gallego leading Lake, 50.0 percent to 47.9 percent, which translates to a vote margin of 52,581 votes according to the CNN elections page.

In order to win the race, Lake would have to capture approximately 545,000 of the remaining votes, which would mean a support factor of approximately 53 percent, or an increase of about five percentage points from her current tally.

In the current count, Rep. Gallego leads in only five of the state’s 15 counties, but commands 51.6 percent support in dominant Maricopa County, which contains almost 62 percent of the state’s population.

As he has been throughout the election cycle, Rep. Gallego is favored to claim the seat and succeed Independent Kyrsten Sinema as one of Arizona’s two senators. This race, however, is closer than originally predicted and verifies the late polling data that detected a surge in Lake’s favor.

In Nevada, Afghan War veteran Sam Brown (R) leads Sen. Jacky Rosen (D) by 2,188 votes statewide in a race that has yet to be called. Approximately 10 percent of the vote remains outstanding.

In dominant Clark County, which houses approximately 70 percent of the state’s population, approximately 47,367 votes remain to be counted. At this point, Sen. Rosen has 50 percent of the Clark County vote as compared to 44.5 percent for Brown. For a Republican to win a Nevada statewide race, however, he or she needs approximately 44 percent of the Clark County vote, so Brown is well within victory range.

In the state’s remaining 16 counties, approximately 79,578 votes remain. For Brown to upset Sen. Rosen, he would need to attract 47.5% of the outstanding vote since he currently leads the statewide tally by 2,188 votes according to the CNN election results Nevada page. Therefore, this race is very much alive for either candidate.

The third and final outstanding Senate race lies in the Commonwealth of Pennsylvania. Here, challenger David McCormick (R) leads veteran Sen. Bob Casey Jr. (D), by 30,669 votes from approximately 6.81 million ballots cast. The CNN election results page suggests that 97 percent of the total vote has been counted, meaning just over 62,000 votes remain if the total vote estimate is correct.

If so, this would mean that Sen. Casey would have to attract a full percentage point more than his current total from the remaining vote number, understanding that three independent and minor party candidates are attracting a combined 2.6 percent.

While Rep. Gallego is in the prime position to capture the Arizona seat, the two Republicans in Nevada and Pennsylvania are mathematically in slightly better position to win their respective elections simply because their current leads mean they need less of the outstanding vote than their opponents.

While the mathematics suggest that both challengers Brown and McCormick have the easier path to victory, such may not be the case in the real world of politics.

With the Republicans sitting at 52 seats in the new Senate, winning either Nevada or Pennsylvania would bring them to 53, while taking both would create a 54R-46D chamber split. This would put them in prime legislative position for the coming congressional session.
