According to Delaware County Clerk Rick Spangler, as of Monday morning 13,593 voters had cast early ballots locally, and the line of those wanting to vote was "lined around the block" outside the County Building about 9:30 a.m. Monday. Spangler said those in line at the time of the noon deadline would be allowed to cast ballots.

Biden chatted with voters as he waited in line to cast his ballot, and helped push an older woman in a wheelchair who was ahead of him. The president waited in line for about 40 minutes before he cast his ballot. He handed his identification to the election worker, who had him sign a form and announced: “Joseph Biden now voting.”

During September’s primary election, Henry won the Democratic nomination for New Castle County Executive over former New Castle County President Karen Hartley-Nagle, receiving just over 60% of the votes.
