Ron , You need to read more on your polotics ! That is because, both Santorum & Doug Walgren was elected to the UINTED STATES CONGRESS 1990 !

US Congressman Doug Walgren lost to Santorum in 1994 . When Santorum painted him as a CARPETBAGGER ! ( Pittsburgh Tribune Review )

Santorum of Lusburg Va is saying at one time, he is a resident of Pa . He has also said that he is not of Pa . The senator has to prove to Pa that he is one , not just a visitor from Va ! ( Pitssburgh Post Gazette ) That is why the voters of Butler , will tell him Nov 7 Stay in VA . When they VOTE BOB CASEY JR , FOR US SENATOR !
