While one PPP poll finds the state's elected Democrats rather popular, another new PPP poll finds Rep. Mike Castle (R-Del.) leading Atty. Gen. Beau Biden (D) in a potential 2010 Senate special election.

Castle leads Biden by 44%-36% margin, with 20% undecided. Castle (54%/33%) holds slightly higher approval and disapproval ratings than Biden (49%/27%).

Despite Castle's lead in the poll, the nine-term congressman said yesterday that the Senate is not on his mind...yet.

"While it's always nice to be ahead in the polls, they will not influence my decisions for the 2010 election. I haven't closed any doors on my political options, but at this time, my priority remains the needs of our state and its representation in the House of Representatives," Castle said in a statement, according to the Wilmington News Journal.
