You could take the informal 7-Eleven “coffee cup” poll with a grain of salt, but the “purple” (Speak Up) cups are in the lead (40% nationally) and I don’t think they’re voting for Hillary Clinton.
Your link sent me to the Onion.
If we were to take the 7-11 cup poll seriously, we have to recognize it is biased. They don’t have enough 7-11s in many of the red states to include those states in their poll. In 2012, Obama won the 7-11 cup poll by 16 points, and the election by 4 points. Thus, a 14 point bias. Currently, Clinton is running 2 points ahead of Trump. Taking bias into account, this means Trump is going to win by 12 points.
