The state teachers union led the way in lobbying state government over the first six months of 2014, according to a report released Tuesday by ethics regulators.

A report from the Joint Commission on Public Ethics found lobbyists spent a combined $109.8 million trying to influence state government — a 4 percent increase from the same time period in 2013.

The top spender from January through June was the New York State United Teachers union, which spent more than $2.6 million.

On the city-wide level, the United Federation of Teachers spent $718,306 on lobbying activities and compensation, making them rank sixth overall.

NYSUT often spends heavily on pushing education issues in the halls of the Capitol. This year was an especially busy one, given the fights over the implementation of the Common Core standards, as well as eventual alterations to how they impact students and later the state teacher evaluation law.

Coming in second was a coalition backed by gambling interests that opposes casino expansion, which spent $1.47 million.

And the Public Campaign Action Fund, an organization that supports the public financing of political campaigns spent $1.36 million. The push for public financing is becoming a perennial issue in Albany and one that’s currently being fought out at the ballot box. A political action committee that backs public financing, Friends of Democracy, is spending heavily on behalf of Senate Democrats to create a public financing program.

This past legislative session brought the creation of a public financing program, but only for the state comptroller’s race this year. Republican Bob Antonacci is participating in the program; Comptroller Tom DiNapoli is not.

Meanwhile, the Greater New York Hospital Association spent $1.1 million, with the bulk of that money going to direct compensation.

The top shop when it came to compensation for the first half of the year was Wilson Elser Moskowitz Edelman & Dicker, which posted $5.6 million in compensation and expenses. They were followed by Park Strategies, which posted $3.9 million.
