BROOKLYN, N.Y. ― New York Gov. Andrew Cuomo survived a primary challenge on Thursday night, but his once impregnable political machine sustained heavy damage across the state as progressive insurgents threw out conservative incumbents down-ballot.

In a state Democratic primary with national implications, Cuomo cruised to a double-digit victory over actor Cynthia Nixon as machine-backed incumbent Lt. Gov. Kathy Hochul fended off New York City Council member Jumaane Williams. A wide-open race for the party nomination for attorney general ― one of the most closely watched contests in the country on the American left ― ended in victory for another machine candidate, New York City Public Advocate Letitia “Tish” James.

But after getting hammered in the state’s marquee races, progressives dominated contests in the state legislature. Left-wing primary challengers effectively ended the Independent Democratic Conference ― a coalition of Democrats who conferenced with Republicans to block Democratic control of the state legislature with Cuomo’s tacit consent.

Fearing Nixon’s challenge, Cuomo brokered a deal to disband the IDC in April, but activists wanted to punish the lawmakers for their betrayal and ensure they never again left the fold.
