Senate Map Tightens as Democrats Hold Polling Edges Across Six Toss-Up States

RealClearPolitics polling averages show Democratic candidates ahead in six of seven Senate contests rated as toss-ups, while the lone Republican advantage in Iowa remains under one percentage point.

With less than seven weeks remaining before the Nov. 3 midterm elections, polling averages across the Senate’s most competitive races show Democratic candidates holding numerical leads in six of seven contests currently classified as toss-ups.

The latest RealClearPolitics averages identify Texas, Michigan, Maine, Alaska, Ohio, Iowa and New Hampshire as the seven toss-up Senate contests. Democrats currently lead the averages in every one except Iowa.

The margins remain narrow across much of the map, meaning the averages represent current measurements of polling rather than predictions of the November results.

Texas has emerged as one of the most closely watched contests.

Democratic state Rep. James Talarico holds a 2.6-point advantage over Republican Attorney General Ken Paxton in the current RCP average, 47.6% to 45%. RealClearPolitics classifies the race as a toss-up.

Recent polling has consistently placed Talarico ahead. RealClearPolling reported this week that Talarico led eight of the 10 surveys then included in its average, while Paxton led one and another was tied.

Michigan presents another close contest, with Democrat Abdul El-Sayed facing Republican Mike Rogers for an open Senate seat.

El-Sayed leads the RCP average by 1.8 points, receiving 46.5% compared with Rogers at 44.7%. RCP also categorizes Michigan as a toss-up.

Seven of the 10 surveys included in the polling set cited in the supplied data showed El-Sayed leading, while two had Rogers ahead and one was tied.

In Maine, Democratic candidate Troy Jackson is challenging Republican Sen. Susan Collins.

Jackson currently holds a 2.5-point RCP advantage, 47.9% to Collins’ 45.4%. RealClearPolitics lists the race as a toss-up as Collins seeks another term.

Six of the seven surveys cited in the current polling set placed Jackson ahead, while one showed Collins leading.

Alaska is operating with a much smaller polling sample.

Democrat Mary Peltola leads Republican Sen. Dan Sullivan by 2 points in the RCP average, 49.7% to 47.7%. Only three surveys were included in the polling set described in the supplied material, with two showing Peltola ahead and a New York Times/Siena survey giving Sullivan a 2-point advantage. RCP currently rates the contest a toss-up.

Ohio’s special Senate election gives Democrats their largest polling advantage outside New Hampshire among the seven RCP toss-ups.

Former Democratic Sen. Sherrod Brown leads Republican Sen. Jon Husted by 3.2 percentage points, 48.6% to 45.4%, in the current RCP average.

Four of the five surveys cited in the polling set show Brown ahead, while one gives Husted the advantage.

Brown is seeking to return to the Senate after losing his seat in the 2024 election. Husted is serving in the seat following his appointment.

New Hampshire currently has the largest Democratic polling margin among the seven toss-up contests.

Democratic Rep. Chris Pappas leads Republican former Sen. John Sununu by 4 points in the RCP average, 45.5% to 41.5%.

The underlying polling remains limited. Of the three surveys cited in the supplied polling set, one placed Pappas ahead, another showed Sununu leading and the third was tied.

New Hampshire was added to the toss-up category this week after previously being rated Lean Democrat by the Cook Political Report. Cook said public and private polling had shown a closer contest between Pappas and Sununu than the previous rating reflected.

Iowa is the only one of the seven RCP toss-up races where a Republican currently holds the polling-average advantage.

Republican Rep. Ashley Hinson leads Democrat Josh Turek 44.2% to 43.8%, giving her an RCP margin of 0.4 percentage points — effectively the roughly half-point advantage described in the supplied data.

The recent surveys cited in the polling set are evenly divided, with two placing Hinson ahead and two giving Turek the lead.

The seven contests are particularly significant because Republicans currently control the Senate with 53 seats. Democrats hold 45 seats, while independent Sens. Bernie Sanders of Vermont and Angus King of Maine caucus with Democrats, creating an effective 53-47 party division.

That means Democrats would need a net gain of four seats to reach 51 and control the chamber outright, assuming no other changes in party alignment.

A 50-50 Senate would leave Vice President JD Vance available to cast tie-breaking votes on matters that divide evenly along party lines.

Thirty-four Senate seats are scheduled for election in November.

The latest Cook Political Report ratings reinforce how concentrated the most competitive portion of the Senate map has become.

Cook’s Sept. 15 ratings place Alaska, Iowa, Maine, Michigan, New Hampshire, Ohio and Texas in the Toss Up category. Five of those seats are currently Republican-held and two are Democratic-held.

Georgia and North Carolina sit immediately outside that category under Cook’s system, with both rated Lean Democrat. Georgia is represented by Democratic Sen. Jon Ossoff, while North Carolina has an open Republican-held seat.

Kansas and Nebraska are the two races Cook currently classifies as Likely Republican. Nebraska moved from Solid Republican to Likely Republican earlier this year, while Cook has described both states as potential additions to the wider battleground if political conditions change.

The remainder of Cook’s Senate ratings contain nine Solid Democratic seats, one Likely Democratic seat, two Lean Democratic seats, seven Toss Ups, no Lean Republican contests, two Likely Republican seats and 14 Solid Republican seats.

Iowa and Texas represent two of the more substantial changes to the Senate map during the summer.

Cook moved both contests from Lean Republican to Toss Up in August, citing public and private polling showing that each had become more competitive. Cook noted at the time that President Donald Trump had carried both states by more than 13 percentage points in 2024.

New Hampshire became the seventh toss-up Monday when Cook moved the contest from Lean Democrat.

Those rating changes do not forecast the eventual winners. Cook defines Toss Up races as its most competitive category, in which either party has a meaningful opportunity to prevail, while RCP’s averages measure the polling included in its calculations at a particular point in the campaign.

The current polling nevertheless shows the unusual breadth of the 2026 Senate battlefield.

Democratic candidates presently hold RCP average advantages in Texas, Michigan, Maine, Alaska, Ohio and New Hampshire, ranging from 1.8 points in Michigan to 4 points in New Hampshire. Republican Ashley Hinson’s advantage in Iowa is 0.4 points.

With five Republican-held seats among Cook’s seven toss-ups and Democrats needing a net gain of four seats for an outright majority, those closely divided contests will account for much of the competition over Senate control through Election Day.
