Just four percent of philanthropic donations in any given year support advocacy work, despite a long track record of success for advocacy campaigns: Everything from helping to end Apartheid in South Africa to enhancing LGBTQ rights in the United States. So why isn’t there more of this support? The Stanford Social Innovation Review article titled When Philanthropy Meets Advocacy looks into the question. And in this podcast, the article's co-author and Bridgespan partner, Susan Wolf Ditkoff, speaks with The Business of Giving host Denver Frederick about the options available to and hurdles in front of philanthropists who wish to get more involved in advocacy.
