In early February, Mr. Steyer gathered two dozen of the country’s leading liberal donors and environmental philanthropists to his 1,800-acre ranch in Pescadero, Calif. — which raises prime grass-fed beef — to ask them to join his efforts. People involved in the discussions say Mr. Steyer is seeking to raise $50 million from other donors to match $50 million of his own.
The money would move through Mr. Steyer’s fast-growing, San Francisco-based political apparatus into select 2014 races. Targets include the governor’s race in Florida, where the incumbent, Rick Scott, a first-term Republican, has said he does not believe that science has established that climate change is man-made. Mr. Steyer’s group is also looking at the Senate race in Iowa, in the hope that a win for the Democratic candidate, Representative Bruce Braley, an outspoken proponent of measures to limit climate change, could help shape the 2016 presidential nominating contests.
Mr. Steyer poured tens of millions of dollars into a successful 2012 ballot initiative in California that eliminated a loophole in the state’s corporate income tax and dedicated some of the resulting revenue to clean-energy projects. He also has helped finance opposition to the Keystone XL pipeline, appearing in a series of self-funded 90-second ads seeking to stop the project.
Those efforts cemented his partnership with Chris Lehane, a California-based Democratic strategist, and heralded the emergence of NextGen Climate, now a 20-person operation encompassing a super PAC, a research organization and a political advocacy nonprofit. The group employs polling, research and social media to find climate-sensitive voters and spends millions of dollars in television advertising to try to persuade them.
