CNN: Only One PA Key Player

CNN has set up a list of key players at the Democratic National Convention. They have 19 brief profiles. Although Pennsylvania has a number of big names at the convention: Sen. Bob Casey, Jr., Gov. Ed Rendell, assorted congressional representatives, etc., only one Pennsylvanian made their list: 8th district Congressman Patrick Murphy.

You can see the profile and the list of others here:
