Exit polling showed Carper defeated Republican Kevin Wade and Independent Alex Pires.
The Senate race was marked by sharp personal attacks against Carper from Pires, who accused Carper of hiding a serious health problem, being corrupt and lying about his military record.
Carper wants to use his third term to continue fighting government waste and inefficiency, work on implementing a deficit reduction plan, revising the tax code to bolster economic activity, and working to make the health care system more efficient.
