Sean is running as a climate hawk scientist, cleantech entrepreneur, and job creator. Climate Hawks endorses this scientist for Congress – and to take the seat away from a science-denying Republican, Peter Roskam, who calls climate change “junk science.” 

He’s specialized in combined heat and power, a technology that involves turning “wasted” heat into power, sometimes achieving double the energy efficiency of the overall US electric grid. He’s chaired a combined heat and power trade association, and testified to Congress on its benefits. And cleantech nerds will delight in his well-crafted, detailed energy/climate policy.

Sean has already been endorsed by two distinguished members of our board of directors: Bill McKibben, founder of, and Jigar Shah, founder of SunEdison. Bill says: “Sean has the right combination of feistiness and knowledge to make him a force for the good in DC.” And Jigar says: “Sean is more than a scientist. He’s a practical entrepreneur and we need his experience in Congress to encourage clean energy projects.” Equally important, Climate Hawks Vote members in the district overwhelmingly preferred him to all of the other candidates put together. In our in-district survey, 79% of the people responding voted for him.

The winner of the early (March 20, 2018) primary will face Peter Roskam. Here are three not-so-fun facts about why Roskam needs to go. He considers climate change to be “junk science.” He voted against Hurricane Harvey relief. And he now chairs the tax policy subcommittee of the House Ways and Means Committee; in other words, the monstrous tax scam bill rushing through Congress right now has Roskam’s fingerprints all over it.

Democrats can—and must—win this district to flip the House back to Democratic control and check the Trump regime’s assault on our climate. The Chicago suburban seat is a “Clinton-Republican” district, meaning that in 2016 the district voted for both the Democratic candidate for President and the Republican incumbent in Congress–and now it’s a top target for Democrats in 2018. Your help can help us go into the primary to help the fiercest climate hawk with a good shot at winning—Sean Casten. Can you help chip in to elect Sean?
