Gleason: Palin will help GOP win 'four or five' congressional seats in Pa.

Republicans nationally and in Pennsylvania tout the energy vice presidential nominee Sarah Palin has injected in the GOP base.

On Tuesday, it caused state party Chairman Bob Gleason to make a bold prediction: Republicans will win back "four or five" congressional seats in the Keystone State.

Generic ballots between Republicans and Democrats show a dead heat, Gleason said, "and that's caused Democrats to be very nervous about their congressional seats."

The chairman, joined by congressional candidate Craig Williams for the state's 7th Congressional District, spoke to reporters on a conference call hours before Democratic vice presidential nominee Joe Biden campaigned in the Philadelphia suburbs.

The GOP appears to have its best shot at winning back seats in northeastern Pennsylvania, where Republicans Lou Barletta and Chris Hackett are in tight races with their opponents. Barletta is locked in a heated battle with longtime incumbent U.S. Rep. Paul Kanjorski (D-Nanticoke) in the 11th Congressional District, and Hackett is facing first-term U.S. Rep. Chris Carney (D-Dimock) in the conservative 10th Congressional District.
 
Republican chances outside of NEPA appear less positive. An internal poll released by Melissa Hart's campaign showed her down five points to U.S. Rep. Jason Altmire (D-McCandless), a rematch of their 2006 battle when Altmire unseated her.

Gleason also pointed to Williams' race against U.S. Rep. Joe Sestak (D-Edgmont) as a potential Republican victory.
