The ubiquitous U.S. corner store 7-Eleven is helping with an unlikely type of convenience: polling in the upcoming U.S. election. For the last three elections, the store has made red and blue cups to represent the candidates. When customers come to get their coffee, they have the opportunity to "vote" for one of the two main parties. For the upcoming election, that data will be included in the 7-Eleven Election API, so developers can have ready access to the current entirely unscientific polling numbers.
