The new Rasmussen poll of the Delaware Senate race, conducted yesterday in the aftermath of conservative activist Christine O’Donnell’s upset win in the Republican primary, shows Democratic New Castle County Executive Chris Coons with a double-digit lead.
The numbers: Coons 53%, O’Donnell 42%. The survey of likely voters has a ±4.5% margin of error. In the previous Rasmussen survey from two weeks ago, Coons led O’Donnell by 46%-36% — and Rep. Mike Castle, the moderate Republican who O’Donnell defeated on Tuesday, led Coons by 49%-37%. The TPM Poll Average gives Coons a lead of 52.2%-38.8%.
From the pollster’s analysis: “The Delaware race is now viewed as Solid Democrat in the Rasmussen Reports Election 2010 Senate Balance of Power rankings. This marks a remarkable turnaround in a race that at the beginning of the month was rated Solid Republican and was on track to be a GOP pickup. At that time, Congressman Mike Castle led Coons as he had been leading all year.”
