Senate Control Hinges on 13 Tight Races and Pacific Northwest Votes

Voters across the United States are casting ballots on Tuesday, November 3, 2026, to determine which party will control the U.S. Senate for the final two years of President Donald Trump's second term. This midterm election is being viewed as a referendum on the administration, with many citizens expressing frustration over high prices and an unpopular war with Iran. 35 of the 100 Senate seats are at stake, comprising 33 regular elections and two special elections to fill the seats of Marco Rubio and JD Vance. Winners of these contests will begin their six-year terms on January 3, 2027.

The current balance of power is precarious for the Republicans, who hold 53 seats, while Democrats hold 45 plus two independents who caucus with them. Democrats need a net gain of four seats to secure a majority in the upper chamber. In contrast, Republicans can afford to lose only two seats to maintain their control. Ballotpedia notes that 11 senators are retiring or not running again, including four Democrats and seven Republicans. This high number of retirements has opened several key seats, particularly in states that voted for President Trump in 2024, making the path to majority control uncertain for both parties.

Analysts have identified 13 specific Senate races as battlegrounds where the outcome will likely determine the chamber's control. These races include contests in Alaska, Florida, Georgia, Iowa, Kansas, Maine, Michigan, Montana, Nebraska, New Hampshire, North Carolina, Ohio, and Texas. The ratings for these races vary among major election forecasters. For instance, Maine is currently rated a toss-up by all four major trackers, while Iowa is seen as either a toss-up or a slight Republican lean. In Alaska and Michigan, the races are viewed as toss-ups with a slight Democratic lean, whereas Georgia is seen as leaning or likely Democratic.

The Pacific Northwest and surrounding regions are central to this calculation, with polls open in Oregon, Idaho, and Alaska. In Oregon, polls are open from 7 a.m. To 8 p.m. Local time, with both an open Senate seat and an open governor race on the ballot. Idaho voters can cast their ballots from 8 a.m. To 8 p.m., where incumbent Senator Jim Risch is running for reelection and Governor Brad Little seeks another term. In Alaska, polls are open from 7 a.m. To 8 p.m., featuring incumbent Senator Dan Sullivan in a race rated as a toss-up to lean Democratic by some groups. Notably, the Trump administration has filed a lawsuit related to the certification of the Senate result in Alaska, adding a layer of legal scrutiny to the state's election process.

Key matchups in the battleground states have drawn significant national attention. In North Carolina, former Governor Roy Cooper is challenging former Republican National Committee chair Michael Whatley for the seat of retiring Senator Thom Tillis. In Georgia, Senator Jon Ossoff faces Representative Mike Collins in a race that is leaning Democratic. In Ohio, former Senator Sherrod Brown is competing against incumbent Senator Jon Husted. In Michigan, former Representative Mike Rogers is running against Abdul El-Sayed, a race that has seen late endorsements shift the dynamic as El-Sayed's former primary opponent Haley Stevens backed Rogers.

In Texas, Republican Attorney General Ken Paxton, who was backed by President Trump in the primary over Senator John Cornyn, is facing Democrat James Talarico. In Maine, incumbent Senator Susan Collins is clashing with former state Senate President Troy Jackson, a race that has become competitive due to economic strain and tariffs. New Hampshire presents a contest between Representative Chris Pappas and former Senator John E. Sununu for the seat of retiring Senator Jeanne Shaheen. These races are critical because they represent a mix of states that voted for Trump in 2024 and states that are traditionally competitive or lean Democratic.

More than 57 million people had already voted as of Monday, surpassing early vote totals from four years ago in many closely watched states. This high level of early voting suggests that turnout will be a decisive factor in the final tallies. Republican National Committee Chairman Joe Gruters stated that everything depends on turnout, emphasizing that if their voters show up, they will win. Conversely, Democratic Congressional Campaign Committee Chair Suzan DelBene argued that the American people are angry and want change, reflecting the party's strategy to capitalize on dissatisfaction with the current administration.

President Trump has been actively campaigning for his party, holding dozens of rallies and ending his recent schedule in Salina, Kansas, where he urged supporters to pretend he was on the ballot. His administration has also been involved in legal battles over voting procedures, including a temporary bar against a plan to prevent noncitizen voting and an order to stop demanding that California segregate ballots from suspected noncitizens. Critics argue these moves risk disenfranchising eligible voters, while supporters say they are necessary to ensure election integrity. The Justice Department has threatened to prosecute local election officials, a move that has raised concerns among Democrats about potential interference.

The financial aspect of the 2026 elections is also historic, with the campaigns likely becoming the most expensive in American history. Republican committees have outraised and outspent their Democratic counterparts, aided by Trump-affiliated groups and Elon Musk. However, at the candidate level, Democrats have managed to outraise their opponents. An analysis of AdImpact data shows that 88.1% of Republican general election TV ad spending went to states and districts that Trump won in 2024, with more than $850 million spent in areas where he won by 10 points or more. This spending strategy reflects the Republican goal of defending their Senate majority in states they consider safe.
