After Beau Biden (D) decided against running for his father's Senate seat this year, Democrats warned against writing off Chris Coons (D), the New Castle County Executive and likely nominee. But a new Rasmussen poll (4/29, 500 LVs, MoE +/- 4.5%) shows he still has a steep hill to climb as he runs against Rep. Mike Castle (R).

General Election Matchup
Castle 55 (+2 vs. last poll, 2/22)
Coons 32 (unch)
Und 7 (-1)

RCP classifies the race as Likely Republican.

President Obama has a 54 percent approval rating in Delaware, while 46 percent disapprove.
