From their site: Join a national conversation about our future. It’s time to ask our leaders to put partisanship aside in search of real solutions. We need to come together with courage, creativity and generosity of spirit. By using the tag #INDIVISIBLE in our tweets and thoughts, blogs and vlogs, we can amplify our voices. To spark the conversation in our stores, your local Starbucks will proudly serve everyone a free tall brewed coffee on the Fourth of July.
