Who Won Delaware Elections in 2010?
Long-time Representative Michael Castle decided to run for the Senate seat previously held by Joe Biden. Castle's House seat was won by Democrat John C Carney, Jr.
Castle famously lost the Republican primary for the Senate seat to Christine O'Donnell in a small turnout. O'Donnell then went on to lose the election by a wide margin to Democrat Chris Coons. Polls showed that Castle probably would have defeated Coons.
