PoliticsPA has a redistricting update that mentions giving Democrat Tim Holden D-heavy Scranton to make things easier on GOP freshman Lou Barletta, and whether Bill Shuster will want to take on historically Democratic parts of the 12th District in order to give Republicans a better chance in a combined Altmire/Critz district. PA-4 looks to be strengthened for Mike Kelly too, by giving him more of R-friendly Butler County.
