ALBANY, N.Y. (AP) — Liberal law professor Zephyr Teachout launched a primary challenge to unseat Democratic Gov. Andrew Cuomo on Monday, acknowledging her status as an underdog but vowing to run a competitive campaign against the well-funded, popular incumbent.

Teachout, a Fordham University law professor, narrowly lost the endorsement of the left-leaning Working Families Party last month after Cuomo promised to support several liberal priorities, including a higher minimum wage and a broad public campaign financing system.
