Democrats win both chambers despite Republicans outspending them 60% in 2026 midterms

Democrats won both chambers of Congress in the 2026 US midterm elections despite Republicans outspending them by 60%, marking a significant political upset. The record-breaking campaign saw Republicans lose seven stronghold seats, with outside groups spending at least $2 billion on Senate races alone. Voter opposition to data centre projects and a notable shift among Latino voters back to Democrats contributed to the losses. A record 14.5 million Latinos voted, with Republican support dropping 14 percentage points in majority-Latino counties. Wealthy donors like Elon Musk spent heavily, including $316 million backing Texas Attorney General Ken Paxton, but failed to secure anticipated wins.
