Penn Ties Still Hurting Clinton in Pa.

The demotion of Mark Penn in Hillary Clinton's campaign hasn't ended the problem the errant consultant is causing her in Pennsylvania, Bloomberg reports. Unions supporting Barack Obama have pounced on the strategist's advocacy of a Colombian free-trade deal, calling him pro-business and anti-worker. "She has to sever completely with Mark Penn," said Teamsters president James Hoffa. "Her credibility is at stake."

Clinton and Obama are locked in a tight battle in some of the Keystone State's industrial centers, such as Wilkes-Barre and Harrisburg. And while Clinton has generally held an advantage over Obama among blue-collar workers, the Penn fallout threatens to jeopardize her chances.
