Democrats Eye Midterm Gains, but Past Poll Misses Loom
WHO:
CNN - President Trump and some Republicans appeared sanguine about the election in its final days, while many Democrats worried polls might overestimate their candidates’ strength.
CNN - Democratic Senate nominees in Maine and Michigan were not running as well as the Democratic gubernatorial nominees in those states, according to the article.
BBC - Democrats are seeking gains in the midterm elections; the articles say polling has been predicting a Democratic surge.
Silver Bulletin - The New York Times/Siena University polls surveyed seven states in their latest set, after previously polling Minnesota, Florida, South Carolina and Nebraska.
Silver Bulletin - The article identifies Pete Ricketts as the Republican incumbent in Nebraska and Ashley Moody as the Republican candidate in Florida.
WHAT:
CNN - Democrats need a net gain of four Senate seats and must flip at least two states Trump won by double digits; they are campaigning offensively in only one state Kamala Harris won.
CNN - A hypothetical 10-point shift toward Democrats from 2024 results in every state would still leave them with only 49 Senate seats.
CNN - Republicans’ mid-decade redistricting could provide as many as nine additional House seats, though the article said they were unlikely to win all of them.
CNN - Trump had a 34% approval rating and 64% disapproval rating in CNN’s Poll of Polls, 30 points underwater.
CNN - About three-quarters of Americans said Trump and his administration had not focused enough on affordability. An AP-NORC poll found 54% said Trump did not try to keep his promises; 28% said he tried but failed, and 17% said he kept them.
CNN - CNN and New York Times/Siena polls showed Democrats leading Republicans on corruption by 7 and 11 points, respectively; a CBS News poll found 52% expected corruption to increase if Republicans won the midterms, versus 37% if Democrats won.
BBC - Polling trends suggest Democrats could have a strong midterm election night, but polls have missed before; last-minute decisions and sampling issues mean a predicted surge is not guaranteed.
BBC - In the previous year’s state and special elections, Democrats outperformed most surveys as their voters turned out in unexpectedly large numbers.
Silver Bulletin - The latest New York Times/Siena polls showed Democrats ahead in nearly every Senate battleground and associated governor’s race, including Texas; leads were sometimes narrow and sometimes larger.
Silver Bulletin - The polls showed a Democratic advantage of 11 points on the generic ballot.
Silver Bulletin - In Nebraska, the poll showed Ricketts ahead by 6 points, a stronger result than recent Republican internal polls; in Florida, it showed Moody ahead by 6 points.
Silver Bulletin - The article said no currently Republican-held state other than North Carolina was rated “Solid D.”
Silver Bulletin - After the latest polls, the model’s odds of Democrats winning the Senate rose into the 80-percent range for the first time that evening; the article said the polls had less effect on the model than expected.
Silver Bulletin - The model had been near the boundary between “Lean D” and “Likely D,” with “Likely D” formally defined as a 75 percent chance of winning.
WHERE:
Silver Bulletin - The Senate and governor’s races discussed include battlegrounds across seven states, with Texas, Alaska, North Carolina, Minnesota, Florida, South Carolina and Nebraska specifically named.
Silver Bulletin - The article mentions LaGuardia Airport in an example about waking early to catch a flight.
WHY:
CNN - The article said nonresponse bias, which contributed to polling errors in the 2016 and 2020 presidential elections, could again cause polls—especially in red states—to underestimate Republicans.
CNN - The article cited Trump’s tariffs, the Iran war, and mass-deportation efforts as factors that could weaken his support among voters, including Latinos and White voters without college degrees.
BBC - Past polling inaccuracies, late-deciding voters and sampling issues are reasons the projected Democratic gains are uncertain.
Silver Bulletin - The model adjusts polling firms’ results for “house effects”; it accounts for New York Times/Siena’s tendency to produce favorable numbers for Democrats this election cycle.
HOW:
Silver Bulletin - The model incorporates pollster ratings and adjusts survey results for house effects, including in races the New York Times has not polled.
Silver Bulletin - The author said Democrats might still prevail despite a modest polling error, based on the latest surveys, including some received after the model’s deadline.
(UPDATED November 2, 2026 11:00 UTC)
Polls show Democrats leading across nearly every Senate battleground, raising hopes of a midterm surge. But their path remains difficult: they need four Senate seats and must flip Trump-won states. Past polling errors, late-deciding voters and sampling issues could still make Democrats’ projected gains uncertain.

(UPDATED November 2, 2026 09:58 UTC)
New polls show Democrats leading nearly every Senate battleground, with an 11-point national advantage. The model now gives Democrats an 80-percent chance of winning the Senate. But past polling misses, late-deciding voters and sampling problems make a Democratic surge uncertain.
