Republican Christine O'Donnell will face off against Democrat Chris Coons.
Meantime, Coons, a New Castle County Executive, spoke with a group at the Senior Center on North Market Street in Wilmington Wednesday. He talked about issues facing voters of all ages.
Coons presented the Senior Center with a proclamation in honor of its work to bring the community together.
Coons' opponent, Republican Christine O'Donnell, announced last night that she will not do anymore interviews on national television. Her decision comes after the release of an 11-year-old videotape of O'Donnell talking about dabbling in witchcraft.
She has since said it was just 'teenage rebellion'.
O'Donnell told a cable news program last night that she wants to focus now just on Delaware, following the advice of Sarah Palin.
