New York Gov. Andrew Cuomo and liberal challenger Zephyr Teachout are making their closing arguments before Tuesday’s Democratic primary for governor.

Cuomo planned rallies in New York City and outside Buffalo on Monday, while Teachout appeared on the radio and touted proposals to encourage technological innovation.

Cuomo has support from the state’s Democratic Party, powerful unions and heavyweights including New York City Mayor Bill de Blasio and Hillary Clinton. Teachout, a Fordham University law professor, has galvanized liberal dissatisfaction with Cuomo, and her bare-bones campaign threatens to upend what many believed would be an easy re-election for Cuomo.

The primary winner faces Republican Rob Astorino this fall.

In the Democratic primary for lieutenant governor, Cuomo running mate Kathy Hochul faces Tim Wu, a Columbia University law professor tapped by Teachout.
