A new Rasmussen poll in Delaware finds that Republican Congressman Mike Castle could potentially beat state Attorney General Beau Biden — a son of Vice President Joe Biden — in the 2010 special election for the VP’s Senate seat.
The numbers: Castle 47%, Beau Biden 42%. In addition, Beau leads 2008 GOP Senate nominee Christine O’Donnell, a marketing consultant who lost by 65%-35%, by a smaller but still significant margin of 49%-40%. The margin of error is ±4.5%.
As of right now, neither Castle nor Beau are officially in the race, but they are widely viewed as potential candidates. O’Donnell is the only declared contender for the seat.
