Chris Carney was a superdelegate to the 2008 Democratic National Convention . He vowed that he would " wait and see how his district votes " , hinting that he would likely issue an endorsement after the April 22 Pennsylvania primary for the candidate that wins by a " landslide " — if a huge victory by either occurs — in his overwhelmingly conservative district in which registered Democrats are few compared to Republicans . Another northeastern Pennsylvania Congressman , Paul Kanjorski , had long endorsed and actively campaigned for Clinton , alongside a number of other Democratic politicians in the state , including Governor Ed Rendell , while U.S. Senator Bob Casey , Jr. was Obama 's most significant supporter . Carney endorsed Clinton on May 9 after she carried his district in the Democratic primary by a whopping 70 % -30 % margin
