EDISON - Voters will head to the polls in less than a month to decide if Cory Booker or Steve Lonegan will represent New Jersey in the U.S. Senate.

Booker and Lonegan are facing each other in a special election on Oct. 16 to fill the seat left vacant by Frank Lautenberg.

This week, two different polls have very different takes on the race. Stockton College says Booker is up by more than 25 points, while Quinnipiac University had the margin at just 12 points.

David Redlawsk, a politics professor at Rutgers, says voters should never pay attention to any one poll. "Any poll can be off for a whole lot of reasons, and in this kind of election, it's because we don't really know who's going to vote," he says.

According to Redlawsk, the polls change depending on who the pollsters think will show.

Rutgers' poll had a 35-point margin just two weeks ago.

Both campaigns are spending lots of money to sway voters, and the Lonegan camp has attacked Booker for his time spent fundraising across the country.
