EAST HAMPTON - The owners of East Hampton's The Monogram Shop say they have a proven way to predict who will win this year's presidential election ahead of the big day.

Devon Smith says her store started a poll back in May that counts votes by tabulating the number of President Barack Obama and Mitt Romney plastic cups sold. The poll, which will end on Election Day, has already seen Romney's cup sell out twice.

The latest official cup count saw Romney at 4,000 and Obama at 3,301. Smith says the final results of this poll have never been wrong. This is the third one that The Monogram Shop has held.
