Jack Murtha, whose once-certain re-election has now been put in serious danger after he called his constituents racists and rednecks, has brought out two new weapons in his campaign: Bill and Hillary Clinton, who remain popular after they campaigned throughout the region for the Dem primary, and have recorded robocalls for the embattled incumbent.

Here's the Bill call:

"Jack has been a tireless worker for Western Pennsylvania and indeed for our whole country," Bill says. "His leadership is critical in this time of grave economic uncertainty because he's got a proven track record of creating new jobs and promoting economic development in his district and in a way that's good for everyone."

"Jack Murtha knows Western Pennsylvania; Jack's a true leader," Hillary says. "He fights everyday for you, for our troops, and our veterans, just as he fought for me. I ask you please to support Jack Murtha on November the 4th."

Meanwhile, both parties are fighting hard in this seat. The NRCC's FEC papers from yesterday show they spent $465,000 in last-minute advertising yesterday for the race against Jack Murtha, whose once-safe re-election is threatened by him having called his constituents racists and rednecks. The DCCC also made their own massive buy of $450,000 in TV time, phone banking and mailing.
