The National Journal analyzed the finance of current members of Congress with a particular focus on those members that are "double dipping." That is, elected officials that get paid twice - once by the taxpayers for their current position and again by the taxpayers for a previous one.
PA's double dippers from the National Journal:
Democratic Congressman Robert "Bob" Brady
Democratic Congressman Chaka Fattah
Republican Congressman Jim Gerlach
Democratic Congresswoman Allyson Schwartz
Republican Congressman Charlie Dent
Republican Congressman Joe Pitts
