Former North Carolina Gov. Roy Cooper launched his campaign for U.S. Senate on Monday, setting up a high-stakes battle in one of the nation’s most competitive states and giving Democrats a marquee contender in their push to retake the majority.

Cooper, a two-term governor who left office in January, enters the race to succeed retiring Sen. Thom Tillis (R-NC) with strong name recognition, statewide infrastructure, and a record of winning tough races in a state that has trended red at the federal level. His candidacy immediately reshapes the 2026 Senate map, offering Democrats a rare pickup opportunity in a cycle in which they are largely on defense.
