A new survey of Delaware from Public Policy Polling (D) should cause some level of concern for Democrats. In a possible match-up for Joe Biden's former Senate seat in 2010, Republican Congressman Mike Castle is currently ahead of Biden's son Beau, who was elected state attorney general in 2006.
The numbers: Castle 44%, Beau Biden 36%, outside the Â±3.5% margin of error, though with high undecideds.
Among Democrats, who make up 51% of the sample, Beau leads by 54%-22%. Republicans, at only 29% of the sample, solidly back Castle by 75%-15%. And among others, at 20% of the sample, Castle has a lead of 53%-20%.
From the pollster's analysis: "Mike Castle has served in statewide office now for almost 30 years and that higher level of familiarity with Delaware voters gives him an advantage over Beau Biden. Biden's numbers would surely improve as he became more well known to voters in a statewide campaign but I'm sure the Democrats would nonetheless be quite happy for Congressman Castle to stay where he is."
