A few days ago, we asked you to lend your voice to a new challenge for the candidates, calling on them to visit Africa and see first-hand the opportunities and the challenges that people in those countries face. Already, more than 52,000 people have signed that petition, and we are not finished yet. In the next few days, we will take these petitions and deliver them to the presidential candidates, and see if they are willing to step up and make fighting extreme poverty and preventable disease a real priority. If you haven’t signed the petition, add your voice today.
