Wednesday is showdown day between democrat Cory Booker and republican Steve Lonegan. Voters will head to the polls throughout the day on Wednesday casting votes in a special election to fill the seat of the late U.S. Senator Frank Lautenberg. Booker is a heavy favorite to keep the seat in the hands of his democratic party. Most pre-election polls give Booker a double-digit lead heading into the election. The government shutdown became the latest, and perhaps final, issue before voters go to the polls.
