As they challenge Gov. Andrew Cuomo and his running mate Kathy Hochul for the Democratic ballot line this September, Fordham professor Zephyr Teachout and her running mate Tim Wu have raised a combined $277,360 for the effort.

Teachout had initially sought the Working Families Party ballot line in May, but ultimately failed to garner enough support at the labor-backed party’s convention, losing the endorsement to Cuomo.

Regrouping, Teachout last month launched a campaign to primary Cuomo on the Democratic Party ballot line.

The fundraising total includes $247,000 raised by Teachout and $63,000 from Wu’s campaign account, which includes a $30,000 loan from the Columbia professor.

The campaign spent heavily on an effort to petition its way on to the Democratic primary ballot, with the campaign expenditures totaling $119,050.

Teachout says the fundraising effort — which includes 796 individual donors — is a sign of strong grassroots for her candidacy as an alternative to Cuomo.

“This is an amazing show of support,” Teachout said in an interview. “People really are ready for a Democrat to be on the Democratic ballot line. He (Cuomo) really has abandoned core Democratic values.”
