The other contest that's getting national attention is a special election in Pennsylvania's 12th Congressional district. The seat that was held by John Murtha for 34 years until, his death in February. Democrat Mark Critz, Murtha's former aide, is running against Republican businessman Tim Burns and Libertarian Demo Agoris to serve out Murtha's term. The district includes all of Greene county, and parts of six other counties. Polls show a tight race between Critz and Burns.

There is also a primary contest in district 12 featuring Democrats Mark Critz, Ron Mackell, Ryan Bucchianeri and Republcisans Tim Burns and William Russell.

After 8 years under Governor Ed Rendell, four democrats are vying for the right to represent the party in November's general election for governor.
