The New York State United Teachers decided not to endorse Andrew Cuomo for re-election, nor anyone else.

NYSUT has 600,000 members and a strong get-out-the-vote operation. It did endorse the Democratic Attorney General Eric Schneiderman and Comptroller Thomas DiNapoli.

“Those who earn endorsements are friends of public education and labor,” NYSUT president Karen Magee said in a statement. “Over the last two years, they earned our support by advocating effectively for our public schools, colleges and health care institutions; listening intently to the concerns and aspirations of our members, and voting consistently the right way.”

Cuomo is a staunch advocate of privately-managed charter schools and has received large campaign contributions from the hedge fund industry, which supports charter schools. 3% of the state’s children are enrolled in charter schools. Cuomo is also a firm advocate for evaluating teachers by the test scores of their students, although he gives no sign of knowing that it has been tried and failed in many other places.
