HAMDEN - Southwestern Connecticut's Quinnipiac University is one of the biggest polling operations in the country, and the polls are conducted out of a building behind a Subway store in Hamden.

The polls are frequently cited by media outlets across the United States and are often called the nation's most influential political surveys. Officials say the polls often influence the amount of funding candidates receive.

"Our bread and butter is politics," says pollster Doug Schwartz. "We do the best that we can to get it right."

Schwartz says 150 interviewers can call hundreds of numbers in just three hours.  It takes up to a week to gather the results of just one poll.

Another group of monitors oversees the interviewers, making sure they are unbiased.
