A convenience store is using a very unscientific way to determine the President of the United States.
7-11 is conducting their own poll to determine the winner by using coffee cups.
Nothing beats a fresh cup of coffee first thing in the morning.
But can brew predict if Mitt Romney or President Barack Obama will win the 2012 Presidential Election?
Red and blue cups were stacked neatly outside the 7-11 Mobile Oval Office that rolled into town Saturday morning.
The tour bus has visited with voters in 20 major cities since September, asking them to choose who will to sit in the real Oval Office.
"They wanted me to pick one, I told them I'm undecided so I'm keeping the balance, one of each," said Zack Gussey, an undecided voter.
The poll is unscientific but 7-11 says its has successfully predicted the winner of the past three presidential campaigns.
"We get within three or four margin points, it's that close," said Ray Kruckner, market manager of Arizona 7-11 stores.
Kruckner said every cup counts and every vote can be tracked online.
So far, President Obama has the lead in Phoenix and Mesa but Romney leads in Gilbert.
"In all reality, we do need a little bit of fun. We have so much negative slinging going on right now," said Jamie Baker.
Republican or Democrat, these valley voters will keep a close eye on the results Tuesday, eager to see if their 7-11 pick makes a difference.
Votes will count until election day. You can buy your Obama or Romney coffee at any valley 7-11, or there are nuetral cups in case you don't want to revel who you plan to vote for.
