PHOENIX (CBS5) -
It's far from official, but people buying drinks at 7-Eleven always seem to predict who wins the White House.
The convenience store chain has correctly predicted the results for the past three elections.
This year, it's getting into the political spirits again, offering customers free coffee the morning of Sept. 28 and inviting them to cast their unofficial ballots for the store's poll.
The events falls on the day before National Coffee Day on Sept. 29.
