## Current polling projections
Forecasters and prediction markets favor Democrats to take over the Senate with 65% to 80% chance of reestablishing majority they lost two years ago.
## Key Senate races
Democrats lead in Texas, Kansas, Michigan, Maine, Ohio, Alaska and Iowa with margins ranging from 1 to 11 percentage points.
## Polling blind spot
Registered white Democrats are about 30% more likely than registered white Republicans to respond to polls, creating nonresponse bias.
## Historical polling errors
Times/Siena polls underestimated Trump by 5 percentage points in 2020, with similar gaps in 2016 and 2020.
## Polling adjustments
Times/Siena adopted new weighting process this summer to correct for response gaps but accuracy remains uncertain.
## Polling methodology
Polls have changed how they analyze public opinion to prevent flawed forecasts from recent elections.
## Past accuracy
Times/Siena polls were accurate in 2018 and 2022 despite higher Democratic response rates.
## Current polling uncertainty
Even a 75% chance of Democratic Senate win leaves Republicans a real path to holding the chamber.
## Final poll results
Democrat Abdul El-Sayed leads former Rep. Mike Rogers by 11 points in Michigan, the only Democratic-held seat of the seven.
## What the polls say
Polls show Democrats leading in all seven key races with margins from 1 to 11 percentage points.
## Key takeaway

Polls project Democrats winning Senate majority but historical sampling gaps could lead to underestimation of Republican support.
