Four major races shift in favor of Democrats as Senate looks more likely to swing in their favor

The Cook Political Report shifted four Senate races to favor Democratic candidates as the minority party looks increasingly poised to flip the upper chamber.

Cook is known largely for its ratings of how elections might tilt. Democrats hold 47 Senate seats, meaning they need to flip four seats to win the majority. To do so, they will need to hold two Senate seats–in Michigan and Georgia — in states President Donald Trump won in 2024 — and flip at least four Senate seats.
