Politico's Scorecard reports:

Former NRCC chairman and political junkie Tom Davis is throwing in the towel on Republican Jim Tedisco's chances of overcoming his 273-vote deficit against Democrat Scott Murphy in the New York special election.

"We lost the special election in New York. It's gone,” Davis told the Washington Times.

My posts on this are becoming a bit redundant, so unless something swings dramatically toward Tedisco, this is probably the last one.  The New York Board of Elections has the count at a 273-vote Murphy lead, and it is pretty hard to see how he overcomes that.  Tedisco's best course of action is probably to give a gracious concession speech to try to avoid Ellen Sauerbrey Syndrome (the pun "Ellen Sourgrapes" nearly wrote itself), and look to 2010.
