a man who defeated her by approximately 30 points. i sat down with vice president joe biden this afternoon and i asked him straight off about christine o'donnell. mr. vice president, thank you so much for your time. i really appreciate this. >> absolutely. >> the republican nominee for your old senate seat in delaware is not long-time congressman mike castle, but rather christine o'donnell who you have run against in the past. her own party has derided her as unelectable to any office and they, in fact, ran robo calls that called her a fraud. it's a very surprising result. how do you explain that vote in your home state? >> it's hard to explain. first of all, there are -- we're a single congressional district state. we're a small state, only five smaller. 185,000 roughly republicans registered in the state of delaware, closed primary. she got roughly, what 25,000 to 28,000 votes out of 50,000 cast.
