Petition signer, First, thank you for signing our petition asking Senator Warren to endorse Bernie Sanders for President. We just reached 15,000 signatures. Please go to the Change dot org website and use the share buttons (again for many of you) to use social media to help get the word out about this petition. Each signature sends you an email, and she needs to hear from thousands more Americans. In solidarity, Victor Tiffany, co-founder - Revolt Against Plutocracy
