      <PrimaryExemptPurposeTxt>The Center for Election Science is a nonpartisan nonprofit comprised of voting system experts and activists dedicated to helping people make better collective decisions. We pursue election-related scholarship, educating the general public, and promoting voting methods that most benefit the public good.</PrimaryExemptPurposeTxt>
      <ProgramSrvcAccomplishmentGrp>
        <DescriptionProgramSrvcAccomTxt>Outreach: Our website continues to host one of the best resources of applied, layperson-friendly voting theory on the internet. In 2015, our site received over 65,000 unique visitors. Our social media reaches nearly 2,000 people who share our content with their friends. We added 15 blog articles to our site discussing voting methods, debate access, ballot access, and anything related to elections. We reached out to a number of organizations to inform them about voting methods.This year we spoke at Liberty Fest, the National Green Party Convention, and the Voting Method and Elections Integrity Symposium. We provided introductory books on voting systems to the nonprofit organization Ethics and Economics Education of New England, as textbooks for a high-school class on political ethics. Our media outreach got us invited on five radio shows and podcasts to talk about our mission and smarter voting methods. Our activities also landed us interviews with MSNBC.com and the Washington Examiner. Consulting: We helped three organizations (the Webby Awards, the Republican Liberty Caucus, and the Hugo Awards) implement better voting methods while simultaneously publicizing our cause. This work on polling led to our flagship reform of Approval Voting being covered in several news sources, including Politico, The Hill, and The Washington Times. Community: We upgraded our server to include user profiles and a discussion forum, to provide a home for the voting-theory community. Under the CES tent, theorists and activists can help each other disseminate voting innovations with much greater efficiency.</DescriptionProgramSrvcAccomTxt>
