Castle increases lead slightly in latest poll

    A new Rasmussen survey shows the Republican with a 12-point advantage over Chris Coons in the campaign for U.S. Senate.

    Delaware’s U.S. Senate race is basically unchanged from last month, according to a new poll.

    According to the latest Rasmussen Reports telephone survey of likely voters, Republican Mike Castle holds a 12-point lead over his Democratic opponent, Chris Coons.

    The longtime GOP Congressman picked up 49% of the vote while Coons got 37%.   Five percent prefer some other candidate, and nine percent are undecided.

    Last month, Castle held a 47% to 36% advantage over the New Castle County Executive. Last month was also the first time in Rasmussen Reports surveying of the race this year that support for Castle dipped below the 50 percent mark.

    Another Rasmussen poll, however, showed much different results than a month ago. Republican Christine O’Donnell, who is challenging Castle for the GOP Senate nomination in a September 14 primary, now runs 10 points behind Coons (46% to 36%). Last month, O’Donnell held a slight advantage over Coons, 41% to 39%.
