He was running against Republican Tom Smith.
Casey, 52, was state auditor general from 1997-2005; state treasurer from 2005-2007; and United States senator starting in 2007.
Senator Patty Murray, Chair of the Democratic Senatorial Campaign Committee, released the following statement congratulating Casey:
Tonight’s results are great for Pennsylvanians and the country. It’s clear Pennsylvania voters saw through the avalanche of negative attacks and reelected Senator Casey because he is exactly the type of strong advocate they need in the Senate. Senator Casey has spent his career standing up for middle class families and against the special interests. I am honored to continue working alongside Senator Casey in the years to come.
