The political action committee of the New York State United Teachers union on Monday spent $463,840 on behalf of Senate Democratic candidates and incumbents, Board of Elections records show.

The filing shows NYSUT’s VOTE-COPE independent expenditure committee spent $96,271 on mailers and polling in support of Democratic Sen. Terry Gipson in the Hudson Valley and opposing his Republican opponent, Sue Serino.

In Buffalo, the group announced spending $125,000 on TV ads shoring up Democrat Marc Panepinto, who is trying to unseat Republican Sen. Mark Grisanti. The group also announced a combined $38,890 on mailers opposing Grisanti’s re-election as well as backing Panepinto.

NYSUT has garnered some controversy in the 60th Senate district. The group opposed Grisanti’s primary race by painting him as a supporter of tax hikes and this month NYSUT was blasted for mailers with images depicting a battered woman. Grisanti today called on the group to apologize for the mailers.

On Long Island, NYSUT spent $145,000 in TV ads opposing Tom Croci, the Republican running for the open seat being vacated by Sen. Lee Zeldin. He faces Democrat Adrienne Esposito.

In another open Senate seat in the Hudson Valley, NYSUT reported spending a combined $96,132 backing Democrat Justin Wagner and opposing Republican Terrence Murphy. The two candidates are competing for the seat held by Republican Sen. Greg Ball, who is leaving the Senate this year.
