General election

Prior to the election, Chris Coons' re-election was considered to be a near certainty regardless of the Republican challenger. The choice of Lauren Witzke, a controversial extremist and believer of QAnon, as the nominee, only cemented this prediction. Networks declared Coons the winner as soon as voting ended, based on exit polling alone. Coons also outperformed Biden (who also once held this Senate seat) in terms of percentage, but underperformed in terms of raw vote, likely due to the lack of third-party Senate candidates.
